Moderator Guidelines

Moderator Guidelines

  • Don’t be mean to users. Be gentle or neutral.
  • Most moderator actions which have a modlog message should include your username.
  • When in doubt about whether or not a user is problematic, send them a DM.
  • Don’t waste time debating/arguing with problematic users.
  • Assume the best, but don’t tolerate sealioning/just asking questions/concern trolling.
  • Ask another mod to take over cases you struggle with, if you get tired, or when things get personal.
  • Ask the other mods for advice when things get complicated.
  • Share everything you do in the mod matrix, both so several mods aren't unknowingly handling the same issues, but also so you can receive feedback on what you intend to do.
  • Don't rush mod actions. If a case doesn't need to be handled right away, consider taking a short break before getting to it. This is to say, cool down and make room for feedback.
  • Don’t perform too much moderation in the comments, except if you want a verdict to be public or to ask people to dial a convo down/stop. Single comment warnings are okay.
  • Send users concise DMs about verdicts about them, such as bans etc, except in cases where it is clear we don’t want them at all, such as obvious transphobes. No need to notify someone they haven’t been banned of course.
  • Explain to a user why their behavior is problematic and how it is distressing others rather than engage with whatever they are saying. Ask them to avoid this in the future and send them packing if they do not comply.
  • First warn users, then temp ban them, then finally perma ban them when they break the rules or act inappropriately. Skip steps if necessary.
  • Use neutral statements like “this statement can be considered transphobic” rather than “you are being transphobic”.
  • No large decisions or actions without community input (polls or meta posts f.ex.).
  • Large internal decisions (such as ousting a mod) might require a vote, needing more than 50% of the votes to pass. Also consider asking the community for feedback.
  • Remember you are a voluntary moderator. You don’t get paid. Take a break when you need one. Perhaps ask another moderator to step in if necessary.

Get spray paint and a nerdy friend that prints this for you

Spray can on a stick.

[–] FishFace@piefed.social 99 points 1 day ago (3 children)

That would be a class IV laser and dangerous to eyesight merely from the light scattered off surfaces you point it at. If you point it at a camera and watch what is happening for a while you could get irreversible eye damage.

There is nothing special about cameras that makes them vulnerable - if you shine such a laser at a person, you'll likely burn them too. If the beam shines or bounces into your eye, you will likely burn your retina before you can even blink.

This is not a meme or a shitpost, it is very dangerous.

[–] TotallynotJessica@lemmy.blahaj.zone 54 points 1 day ago (2 children)

Use eye protection when vandalizing the surveillance state, got it!

[–] stray@pawb.social 9 points 20 hours ago* (last edited 20 hours ago)

Also give eye protection to literally everyone else who might be standing anywhere in the reflective range of the cover, lens, mirrors, and any shiny metallic objects. These lasers can do damage before you even blink.

e: This includes non-human animals as well. If you're okay with potentially blinding a bunch of innocent corvids I guess that's on you.

[–] monotremata@lemmy.ca 27 points 1 day ago (2 children)

Also do it when nobody else is around.

That's good advice regardless of the danger your vandalism poses to bystanders.

[–] brbposting@sh.itjust.works 3 points 23 hours ago

Aircraft don’t always have transponders on so can’t rely on flight trackers

Imagine blinding a [military] pilot even just for the briefest moment. We can’t keep them in the sky on a good day for reasons I don’t understand (they’ll hit commercial aircraft or vice versa!)

Places like Santa Cruz simply fought these spy cams with their voices. Riseeee upppp, no votes for any city councilpeople who are OK Flocking up their own turf

[–] NOT_RICK@lemmy.world 10 points 1 day ago (1 children)

Yeah a multitool with a tungsten carbide blade + a mask is safer

[–] FatherPeanut@pawb.social 17 points 1 day ago* (last edited 1 day ago) (2 children)

I have often wondered how effective it'd be to just use a spraypaint canister on a pole.

Also, dont bring a phone with, at all. Or anyone else. Or any Bluetooth devices. Bad opsec can lead to bad outcomes.

[–] prenatal_confusion@feddit.org 4 points 17 hours ago

I suggest you find a nerdy friend and print yourself this nice tool https://www.printables.com/model/1331669-wasp-spray-can-pole-mount

[–] NOT_RICK@lemmy.world 9 points 1 day ago

I’d suggest a faraday cage, but I’ve recently learned that cops will also use the lack of cell location info as evidence now too. Best to leave it home, maybe even have someone use it for you while you’re, uh, occupied.

[–] grahamja@reddthat.com 5 points 1 day ago

My laser range safety officer class forced me to learn about making sure the range was clear of any metalic objects that could reflect the laser back to the firing point, blinding a shooter. We always just shot during the day instead. Don't these cameras have a glossy finish on a curved chassis that could just... reflect the laser almost anywhere?

[–] baggachipz@sh.itjust.works 3 points 16 hours ago (1 children)

Why not just a baseball bat?

[–] Manalith@midwest.social 3 points 15 hours ago (1 children)

Presumably because it's a camera and a laser could be far enough away not to see who's doing the laser pointing.

[–] baggachipz@sh.itjust.works 3 points 15 hours ago (1 children)

The camera doesn’t see 360 degrees, just sayin’

[–] njm1314@lemmy.world 1 points 12 hours ago

Assuming there is just one.

[–] monotremata@lemmy.ca 57 points 1 day ago (1 children)

A laser pointer is supposed to be limited to a maximum of 5mW, so these are really freaking powerful (200 times stronger). I don't have experience with lasers that strong, because I value my eyesight, and that of my pets. Please learn more about lasers than I know before purchasing something like this.

[–] femtek@lemmy.blahaj.zone 19 points 1 day ago* (last edited 1 day ago) (2 children)

A lot of the lazers from non reputable brands have are more powerful than rated, I think it was styropyro that has videos of it. But also a few sites sell 1w lasers and also it's easy to make as well.

[–] auntieclokwise@lemmy.world 4 points 22 hours ago

And there's lots where they use frequency doubling to make the laser light while having very poor filtering. Meaning that not only is the visible part of the light very dangerous, but the invisible light (which may have unpredictable patterns) can be even higher wattage and far more dangerous because you don't even know its there.

[–] monotremata@lemmy.ca 8 points 1 day ago

Yeah, I certainly wasn't saying these would be hard to get. And yeah, a lot of cheap laser pointers are also dangerous. What I'm saying is basically, "Hey, this is potentially dangerous, read up on this before you reach for your credit card."

[–] ChaoticNeutralCzech@feddit.org 7 points 23 hours ago (2 children)

To hit the sensor, you need to be in shot (by definition). Remember that walking patterns and other minutia can help identify you.

[–] snoons@lemmy.ca 2 points 22 hours ago

Yes, a big one for me is the distance between your eyes. I see so many people covering their face but not their eyes and the bridge of their nose.

[–] SaharaMaleikuhm@feddit.org 2 points 22 hours ago (1 children)

Get a wheelchair or some such nonsense. A cane and practice a limp. Also wear laser safety goggles.

[–] Manalith@midwest.social 2 points 15 hours ago

Try walking with a pebble in your shoe. That'll change your gait and its not something you're faking so it doesn't require focus to maintain.

Damn, that's a big number

[–] zergtoshi@lemmy.world 3 points 21 hours ago

You're right, but for something like a consumer laser pointer that's typically rated in mW it makes sense to write 1000 mW and not 1 W.
It makes clear how vastly different that is from the regular ones.

[–] snoons@lemmy.ca 16 points 1 day ago (3 children)

but that doesn't sound as cool

which also means anywhere that sells them would advertise it as 1000 [GOLDEN PRESENTERS VOICE WITH HIGH REVERB] mW and I feel a lot of people wouldn't know the difference.

[–] fushuan@lemmy.blahaj.zone 4 points 1 day ago* (last edited 1 day ago)

It sounds exactly as cool as it is. 1000mW reads as 10^3 ×10^(-3)W, which reads pretty pointless. At some point in science you just write everything in scientific notation and remove the multipliers altogether.

[–] morto@piefed.social 22 points 1 day ago* (last edited 1 day ago) (1 children)

A tip for you all when you need to damage small objects without getting caught:

Make the best slingshot you can, train your aim and shooting strength, wait for a heavy rain day and shoot ice cubes at it. The rain will impair visibility and muffle the impact sounds, making it much harder to spot you, and there will be no evidence of what hit the object. Also, there's nothing illegal about having a slingshot with you. The rain can make it harder to hit the object, but a few attempts will allow to learn compensate for it

[–] Cevilia@lemmy.blahaj.zone 4 points 16 hours ago

Where I live, police can draw assumptions from the fact you have a slingshot with you, and arrest you based on those assumptions. So you'd need to have a damn good reason you're carrying a slingshot prepared in advance.

[–] curbstickle@anarchist.nexus 25 points 1 day ago (2 children)

I just so happen to be in need of a 1W, 532nm laser pointer!

Are the cheapies (under $100) useful laser pointers, or are the more expensive ones a better choice for a productive use of the laser pointer? Links welcome!

[–] BigDanishGuy@sh.itjust.works 23 points 1 day ago* (last edited 1 day ago) (2 children)

Suitable applications of 1w lasers

  • light engraving
  • ultra light cutting
  • mischief and miscellaneous shenanigans
  • medical (I guess it's in the range for tattoo removal, but power rating for these lasers are stated weirdly)
  • fiber optic communications

Tasks 1w lasers are unsuitable for

  • any kind of pointing, besides cases where you wish to permanently damage your audience.

As I recall the cheap lasers have an issue with the quality of their wavelength. Both in contamination and precision. Which leads glasses not being effective.

[–] kivihiili@lemmy.blahaj.zone 7 points 1 day ago* (last edited 1 day ago) (1 children)

medical (I guess it’s in the range for tattoo removal, but power rating for these lasers are stated weirdly)

for those curious (you probably know this though), lots of these are pulsed, primarily to avoid excessive local heating (burning) of the tissue being lased. these can have peak powers in the kilowatt range!

watts are energy (in joules) divided by time (in seconds), and while relating energy to time is helpful for constant-power applications—and even some certain pulsed applications—the timeframe here is often small to the point of not mattering much, and a direct measure of the total energy delivered is ultimately most useful. nonetheless they are very impressive sounding and goofy, like "oh i work with multi-KILOwatt lasers on the daily :3" hehe

any kind of pointing, besides cases where you wish to permanently damage your audience.

for a single one watt beam of light, absolutely! do not bring those to the school show-and-tell. but there are absolutely lasers this (or even more) powerful used in concert settings and so forth. still, you're very right, care must be taken with them too.

also your point of output contamination is spot on! +1 to avoiding cheap "powerful" lasers :)

[–] BigDanishGuy@sh.itjust.works 4 points 1 day ago

I just wrote "weird" because trying to explain 250mJ delivered in 15ns became too much math to put into a comment I wanted people to read.

That's what fucking around finds out for you. Luckily I never got to the stage in my project where I put on my budget non-certified goggles, and powered on el cheapo laser diode. But if I can help somebody else to not trust the nominal values, then I'll chime in when this is brought up.

[–] curbstickle@anarchist.nexus 4 points 1 day ago (1 children)

Any idea where the quality is appropriate for the task? Like a $300 range or like a $2k range?

[–] BigDanishGuy@sh.itjust.works 3 points 16 hours ago

Honestly, I've got no idea what price range is plausible these days. What I do know is, that I would only buy from someone who knows what they're doing, and who can provide a proper datasheet. But then again I come at this from an electronics angle, so I'd want a datasheet with stats on the beam, like wavelength composition, and heat dissipation etc, and not just forward voltage and current.

If you're looking to buy a finished product, then figure out what regulatory markings it should have, like UL, CSA, CE, and TÜV. Personally I may be European, but I wouldn't be satisfied with a CE marking, it must at least have TÜV before I'd mess with it, and I'd prefer it to be UL listed as well. Anybody can slap CE on a product, but UL and TÜV are actual testing institutions.

[–] Tiresia@slrpnk.net 7 points 1 day ago

If you want to use these in an uncontrolled environment, definitely get the appropriate laser safety glasses (such as these) as well, and have anyone you don't want to blind who are anywhere nearby or in line of sight close their eyes. Even the scattered reflection off glass or the metal of a camera mount can burn people's retinas permanently, and depending on the surfaces it could scatter a few times and still have enough power to cause damage.

This means if a target is near a highway, you could blind passing motorists. If it's near buildings, you could blind people peeking from windows.

Treat a 1W laser like a power tool. Amateurs can learn to use them safely, but you want to learn from guides rather than from mistakes.

[–] snoons@lemmy.ca 24 points 1 day ago

WARNING: Definitely DO NOT point a [1000mW, 532nm laser] at Flock cameras. It totally won't damage the sensor and render the camera ineffective. So please don't consider it, okay?

[–] AresUII@lemmy.world 15 points 1 day ago (1 children)

1000nm light is infrared.

With that attitude!

Also worth noting: Flock cameras and most other ALPRs operate at 840nm, which is perfect for purchasing IR LEDs at their operating wavelength, so you can hide them behind a license plate border to toggle on whenever you drive past one to wash out any details they could pickup.

But a police officer would definitely be pulling you over and citing you if they catch that, so like, be sneaky or vigilant with its use.

[–] Buelldozer@lemmy.today 3 points 1 day ago* (last edited 1 day ago) (2 children)

Subsonic 22LR would be cheaper, more effective, and safer.

[–] auntieclokwise@lemmy.world 2 points 22 hours ago

And you can get it from the side where there won't be video of you doing the deed. A little target practice is a nice bonus.
