MODERATORS
 

Hello - Please take a look at @[email protected] . They have downvoted every single post in 3 communities (over 200 posts) in a very narrow window of time. They either automated their voting, or they are very focused

Hi, Jet. I didn't see this until now since maybe pings don't transfer between instances? Yep, I mass-downvoted the posts in those communities you run (I read every one of them before downvoting looking for anything even vaguely medically sound), because everything I saw existed solely to spread health disinformation in the form of the so-called "carnivore diet". It's interesting you didn't mention what those three communities are: a carnivore community you run, a community for "metabolic health" you run, and a ketogenic community you run. What you also failed to mention is that all of the posts were yours. Only you post to these cesspits; they're your own little microblog wall instead of a community, and they exist solely as a platform for you to spread known health disinformation. Meaningfully engaging on those communities would only add fuel to the dumpster fire you've created, like how engaging with other types of crackpot only amplifies their message.

The carnivore diet is widely debunked pseudoscientific nonsense which directly contradicts the continually strengthening scientific consensus that reducing animal products promotes better long-term health and which is well-known to considerably elevate the risk of chronic diseases like heart disease and cancer compared to a typical omnivorous diet. Full disclosure: I'm a vegan, and obviously I don't like this on ethical grounds, but what you're doing ethically to the animals or the environment isn't all that much worse than a typical western omnivorous diet; I care, but if this were about my pro-animal activism, I would post on /c/vegan and have 10x the impact for animal ethics than I could downvoting niche communities. No, what this is about is that you're slowly killing yourself through your delusions (fine) and then trying to trick other people to follow suit by couching your claims in half-truths and the medicalese analogue of a sovereign citizen's legalese.

There is no clinical evidence that the carnivore diet provides any health benefits.[3][17][18] Dietitians dismiss the carnivore diet as an extreme fad diet,[3][4] which has attracted criticism from dietitians and physicians as being potentially dangerous to health (see Meat ยง Health).[15][17][18]

It also raises levels of LDL cholesterol, which increases the risk of cardiovascular disease.[4] While carnivore diets exclude fruits and vegetables which supply micronutrients, they are also low in dietary fiber, possibly causing constipation.[4][7][5] A carnivore diet high in red meat increases the risks of colon cancer and gout.[7][31][32] The high protein intake of a carnivore diet can lead to impaired kidney function.[33]

Hilariously, this is a generous summary: Wikipedia is almost too brief about these health problems (and excludes some), and as more people like you follow this fad diet, information is likely to keep coming out about how badly it wrecks your long-term health. Unlike you, I'm a vegan for ethical reasons, and so I take health information about my diet as it comes: B12, iron, and zinc deficiency substantially more likely in vegans? Cool. Vitamin D and calcium? Cool. More likely to fracture a bone? Cool. Harder to get a good daily intake of protein (~0.8โ€“1.0g/kg)? Cool. Harder to get lysine for a complete protein? Cool. Dairy fat intake may lower all-cause mortality? Cool. I recognize these, try to compensate for them in my own diet, and also recognize the numerous health benefits of a PBD (especially with whole foods), but I loudly advertise pros and cons to people looking at veganism for their health. I almost always recommend the Mediterranean diet and DASH alongside a plant-based one if someone is concerned only about their health. If I can be intellectually honest about the science in spite of a deeply held ethical philosophy making me want a plant-based diet to be near-universally followable, I expect you to be able to do the same for your fad.

What's especially troubling is that sometimes you're taking real public health problems โ€“ ultra-processed foods, refined grains, hyperpalatable foods loaded with sugar, etc. โ€“ and using that to manufacture opportunistic FUD: "Oh, this isn't the fault of imbalanced diets full of trash; my fad diet is the only way to fix it". I would've done the same thing if someone started /c/smokingsaves and talked about how smoking a pack a day is great for your health and in fact the decline in smoking is what's elevating cancer diagnoses. Your trash is federated to Lemmy.World, where Rule 8.1 prohibits health disinformation; it's also just completely disgusting to spread it in the first place. You're more than welcome to downvote all of my posts in /c/vegan (if I try to run to the LW admins claiming harassment, link them to this comment), except unlike you, I do my best not to platform pseudoscientific horseshit.

PS: Sorry for linking to your mortal enemy, the American Heart Association.

This is exactly the kind of post I would have been happy to have in a discussion in any of the communities you saw fit to downvote the entire post history of.

Mass downvoting is bad for Lemmy as a whole, it makes the entire ecosystem hostile for participation

Nah, spreading lies is the bad thing, not downvoting them.

[โ€“] [email protected] 0 points 2 days ago* (last edited 2 days ago) (1 children)

So what you're saying is you're happy you did all the down voting? And you would do it again?

[โ€“] [email protected] 2 points 2 days ago (1 children)

Nah, next time I would probably just report communities like that to instance admins to hopefully have a better effect. The broader point is that engagement with disinformation doesn't work; it amplifies it. It's why the far-right has surged globally: negative engagement with disinformation is engagement and fuels its reach, and disinformation is an order of magnitude easier to create than it is to debunk.

[โ€“] [email protected] -1 points 2 days ago* (last edited 2 days ago)

Downvoting is negative engagement.

As long as Lemmy is a place for different communities to exist our presence here is a net positive.

[โ€“] [email protected] 11 points 6 days ago

Move to an instance without downvotes. Checking up on peoples voting records and getting them banned for downvoting is appalling imo.

[โ€“] [email protected] 9 points 6 days ago (1 children)

One person choosing to downvote everything in a community hardly makes it vote manipulation.

[โ€“] [email protected] 8 points 6 days ago* (last edited 6 days ago) (1 children)

How do you see that?

Also, people can be pretty dedicated. I have a few fans myself.

[โ€“] [email protected] 3 points 6 days ago (1 children)

Votes are public, you can see them using a instance that shows them (like old mbin), or if you are a moderator of a community the votes are in, or if your a instance admin of any community.

[โ€“] [email protected] 4 points 6 days ago* (last edited 6 days ago) (3 children)

Sure. Votes are public, but the attribution of votes are not public afaik, although not explicitly hidden. Do you have a link providing evidence that its the aforementioned user doing the down-voting?

[โ€“] [email protected] 8 points 6 days ago (1 children)

Votes are public, but the attribution of votes are not public afaik

They are. You can use Tesseract to see every single username that voted on a post/comment.

[โ€“] [email protected] 2 points 6 days ago* (last edited 6 days ago) (1 children)

Ooh I'll have to test that. Thanks!

Tesseract

Do you have a link?

[โ€“] [email protected] 2 points 6 days ago (1 children)
[โ€“] [email protected] 2 points 6 days ago* (last edited 6 days ago) (3 children)

Ahh this is great thank you.

I still don't see how to find out who is down voting what?

Also wow, look at this:

Some mod took action based on this and perma-banned them across the board! Based entirely on @[email protected], frankly, completely baseless speculation.

Whoever that mod is should be removed.

[โ€“] [email protected] 4 points 6 days ago (2 children)

The username associated with every vote, up or down, is available through the ActivityPub API. If your instance doesn't show them (and I believe lemmy instances don't by default) some helpful soul has built a tool to view them. Sometimes it fails for reasons unknown, but it lets you see who's up or down voted a particular post or comment. I believe nom-lemmy interfaces like kbin also show you that information.

[โ€“] lena 1 points 4 days ago (1 children)

Hi, I made this tool. What posts don't work? And I am aware the user option doesn't work, I'm working on fixing it.

[โ€“] [email protected] 2 points 3 days ago (1 children)

Thanks for making it, it's a really handy tool for understanding who's responding to posts.

One post I can't get the votes for is: https://lemm.ee/post/24727759 I'm guessing that's because the community is on a different server, but I can't see an obvious way to get a link to the comment on it's home server when I'm browsing mine. It would be great if there's a way to resolve the correct server via the API, or at least report why it couldn't get the votes.

[โ€“] lena 1 points 3 days ago (1 children)

This post is older than my instance, that's why votes won't fetch

[โ€“] [email protected] 2 points 3 days ago

Aha! That makes sense. Thanks again for a handy tool.

[โ€“] [email protected] 1 points 6 days ago

Wow, great tool!

[โ€“] [email protected] 2 points 6 days ago* (last edited 6 days ago) (1 children)

You have to be a moderator and use "view votes" from the mod menu, and then they will show up at the bottom of the post.

[โ€“] [email protected] 3 points 6 days ago (1 children)

Moderator or administrator?

Also, if its as simple as connecting to the fediverse to expose these data, it seems weird to keep it hidden.

[โ€“] [email protected] 3 points 6 days ago* (last edited 6 days ago)

Just a mod, afaik. I am not an admin of any instance, but I do mod a few comms. But your instance also has to federate that data and to do that has to be on whatever version that added it (I am not sure what version did this tho). If your instance runs some older version of Lenny, it has nothing to show.

I actually find it weird that it's not hidden from the public, since that's unusual. Obviously everything of this nature is tracked (it has to be to work) but it's usually something only an operator of the thing would have access to.

I'm not sure where I sit on it. On one hand, it's nice to be able to have proof of vote manipulation and not just have to take a mod/admin's word for it, but on the other it could easily lead to abuse/harassment.

[โ€“] [email protected] 2 points 5 days ago

Here's a direct example. Just view your comment on something like an mbin instance (the upvotes are "favorites" and the downvotes are "reduces"). Most mbin instances no longer display downvote information.

[โ€“] [email protected] 2 points 6 days ago* (last edited 6 days ago) (1 children)

nope, nothing public. But the LW admins can just do a query against the voting table for this user and verify it easily - hence this post asking them to do so.

[โ€“] [email protected] -2 points 6 days ago (1 children)

Ok so to be clear then, this is just you making up an accusation.

You don't have any evidence?

[โ€“] [email protected] 3 points 6 days ago* (last edited 6 days ago) (1 children)

This is me asking the LW admins to confirm my findings and follow their TOS.

I see the votes on my side, I know its true.

[โ€“] [email protected] 3 points 6 days ago* (last edited 6 days ago) (2 children)

So a quick sentiment analysis with two hypotheses:

'The author of this text {} .'

h0: 'engaging in respectful, normal internet banter' h1: 'is trolling or otherwise being rude.'

Looks pretty respectful.

and their usage patterns:

Looks like someone you might have just decided to have a problem with.z

Edit: So you've edited your post and claim to see the evidence on your side, but still, have not provided anything. Claiming someone is a bot and engaging in vote manipulation is a big claim and requires big evidence. I don't currently believe you since you haven't provided any.

[โ€“] [email protected] 1 points 6 days ago (1 children)

These graphs are interesting, what do you use to generate them?

[โ€“] [email protected] 3 points 5 days ago

it's part of some tooling I've built up over the years to do basic user analysis.

If you ask around I've shared it with many of the regulars. Since Lemmy doesn't have a proper API, this simply uses a headless browser.

[โ€“] [email protected] 0 points 6 days ago (1 children)

I'm not trying to prove anything to you, you're not a lemmy world administrator

This entire post is to ask the Lemmy world administrators to intervene.

[โ€“] [email protected] 3 points 6 days ago (1 children)

you are making an accusation that has already had real consequences and show no evidence to suggest that it's true.

[โ€“] [email protected] 2 points 6 days ago

I thought it wasn't a secret that votes were somewhat public. If they aren't, ok, but that's news to me.

[โ€“] [email protected] 1 points 6 days ago (1 children)

Seems you might be guilty of mass downvoting yourself, by your own suggestion.

Out of interest, which communities do you downvote at 100% daily for multiple days without blocking them?

[โ€“] [email protected] 1 points 6 days ago

None, I block communities I don't like. The post you are referencing, is a idea for lemmy clients to encourage people to use block instead of downvoting.
