They can block specific communities like lemmy.world did with the major piracy community. If they have a problem with a specific community but not the rest of the instance, they didn't need to go so far as to defederate from the entire lemmy.blahaj.zone instance, though given current tensions between the two instances I doubt they'll be missed. Either way, it is a massive strength of the fediverse that when admins make these decisions, users can easily leave and move to another instance with very little hassle
Yiiiiikes
They must have done something that wasn’t a full defed or haven’t done it yet. I literally just had a hexbear user respond to me in a blahaj post
iirc they'll be able to respond to posts that were already loaded into their instance, and you'll be able to see it, but if you respond, they won't see the response.
They're just not accepting any new data from blahaj. Blahaj hasn't defederated from them, so blahaj is happy to accept any new data they throw at it.
