One of the problems with the way federation currently works is if I block US politics on one instance, I still get it en masse from other instances.

Before activity pub, all that duplication of threads would’ve been handled by moderators merging them together. Actually, it wouldn’t even have been so necessary since userscan see the existing thread and just post underneath that.

When blocking a community, we really need a check box to allow us to block the same community on all instances.
