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

Nope - it is far worse than that, it also does not block messages either, only communities.

And worse than that even is that it used to do so, but the so-called "instance block" has actually gotten weaker over time. Imagine receiving notifications to your inbox for WEEKS and WEEKS upon making what you thought was a fairly innocuous comment in Chapotraphouse... and then going through all that again on Lemmygrad.ml! Purity beatings will continue until morale improves.

If you don't like let's say Lemmy.ml, then you are free to either block each and every single user on it individually (which one guy, ptz, actually did that! ), or you are free to leave Lemmy itself (which I did myself, and am now enjoying the fantastic experience on PieFed! ️), or if you can find one you may join an instance that defederates from them (note that no major instances are willing to do so). Welcome to Reddit 2.0! Remember not to say anything bad about Russia, China, or North Korea or you'll be instance-wide banned from communities that you've never even heard of before!

The "instance block" really is horribly misnamed - it should have been called a "community muting" imho. Oh well, what do I know, and here I thought that Lemmy.ml was a community for FOSS enthusiasts, hur-dur I wonder where I could have gotten that silly idea from!? 🤪

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

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

They made a typo. It's 0.19.12.

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

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

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.

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