As usual, reminder that Piefed allows actual instance blocking

[–] gigachad@piefed.social 14 points 3 months ago (1 children)

Does that mean Piefed also blocks comments and posts of blocked instance users to other instances?

[–] rimu@piefed.social 22 points 3 months ago (3 children)

Yes, when you post to a PieFed community on your own instance your post won't be sent to any instances that you've blocked.

Although if you post to a Lemmy community we can't control where they forward it to. It's complicated.

It's complicated.

That's my line!

[–] gigachad@piefed.social 11 points 3 months ago (2 children)

I love complicated! I am trying to understand. Let's say I have blocked lemmy.ml:

  • a ml won't see a post I submitted to piefed.social, and also I don't see a post they submitted to piefed.social
  • ml user posting to lemmy.world can be seen by me and also sees my post to Lemmy.world
  • I cannot interact with lemmy.ml (makes sense)
  • A post crossposted from lemmy.world to piefed.social by a ml user can be seen by me

Did I get it right? This is of course a purely hypothetical scenario, I would never speak bad about our great tankie leaders from lemmy.ml

[–] rimu@piefed.social 3 points 3 months ago (1 children)

Yes, I think so.

Although this one: ml user posting to lemmy.world can be seen by me and also sees my post to Lemmy.world - I'm not sure about that. I doubt you'd see anything posted by a .ml user.

Defederation is another layer of blocking and it works almost the same but slightly differently too.

Honestly I haven't systematically tested all the possible combinations of settings and all the different places where it might have an effect on other instances. It's a lot. Also most of the blocking code was written almost 2 years ago so it's not something I look at often anymore.

[–] DonnyDorko@midwest.social 1 points 2 months ago (1 children)

So on Pyfedi, does the instance have two layers of blocking? Meaning, "block" and "defederation," or is blocking only for users?

[–] Blaze@lemmy.zip 1 points 2 months ago

Blocking is a the user level

Defederation is at the instance level

(and it's called Piefed)

i blocked the tankie instances, but it wont stop tankie accounts from being seen by you, if they comment on another instance. they only pose a problem if they post outside of tech related posts.

Hey, I wanted to confirm something. Does that mean the blocklist of users are sent to the community's instance?

[–] rimu@piefed.social 4 points 3 months ago (1 children)

No, we check your blocklist before sending and just don't send there if it's an instance you've blocked.

[–] asudox@lemmy.asudox.dev 1 points 3 months ago (1 children)

So the user's instance sends the activity? The community's instance doesn't do the sending?

[–] rimu@piefed.social 3 points 2 months ago (1 children)

Oh, now I see what you're getting at. No, if the user and the community are on different instances then the community instance wouldn't know what the user has blocked. What I said earlier assumes you're posting on a local community.

But honestly why wouldn't everyone just be a piefed.social user and post exclusively in piefed.social communities? ;) /s

[–] asudox@lemmy.asudox.dev 1 points 2 months ago

Ah okay, got it. Thanks for the info. Sorry for the previous misunderstanding.
