With debate raging in the Fedi about Threads' federation, I was having a discussion with another user about the recently implemented instance blocks. They pointed out that, blocking an instance simply hides their content from your feed but doesn't prevent your posts from being sent to them. Firstly, is this correct? Is this how instance blocks are implemented in Lemmy? If not, has this been discussed before? I couldn't find such a discussion in Github issues...

It seems that many people have concerns about Meta's use of their data, and would like to opt out of sharing their content with Threads. Is there any way to do this in Lemmy right now, or any plan to implement such a feature?

This post from Eugen Rochko mentions that blocking Threads at the user level "stops your posts from being delivered to or fetched by Threads". Basically, the user-level instance block is bidirectional.

Limited federation mode is a different feature, at the admin level. It doesn't really affect the delivery of posts in either direction, it just hides the blocked instance's content from the global feed. Defederation on the other hand is indeed bidirectional, but again it's on the admin level rather than users'.

I don't know but the mastodon documentation does not mention this: https://docs.joinmastodon.org/user/moderating/#block-domain

Personally I'd expect that anything I post on social media is being public and freely accessible by anyone if they want to. If you don't want the information to be used by others you probably should not share it with the world.

Lol well hey, fair enough. That's much more recent than anything I found, too. I'd be interested in seeing this feature implemented as well. It would be nice to not directly contribute to anything Meta..

There is an interesting thread here showing the "block" behavior is operating as described in the documentation (Hiding), this raises some questions of a true block or just a client filter: https://mastodon.online/@NatureMC/111590515879528415

I'm curious for additional clarity now!

Other people in that thread have pointed out that it isn't showing posts being delivered to Threads despite the block. That should be testable with other instances, but not Threads since it's not receiving any content from Mastodon at the moment. The concerning thing there is the user still being able to view content from people they've blocked, but that seems to be a bug if it's reproducible.
