One of the major issues is replication and propagation of illegal material. Because of the way that content is mirrored and replicated across the fediverse, attacks that flood communities with things like CSAM inevitably find their way to other federated sites due to the interconnectedness of the fediverse.
The only response currently to dealing with these types of attacks, even if they’re not directed at you, is to generally defederate with the instance being attacked. This means whoever was attacking the site with CSAM has won, because they successfully made it so that the community becomes disjointed and disconnected from the rest of the fediverse with the hopes that it will die.
This whole federated system is about whack-a-mole.
I hate politics, so I filter it out. Oh, look, somebody spun up a new instance! Time to filter out the same fucking communities I filtered on every other goddamn instance.
Sports is another one. I hoped everything would end up on fanaticus.social but no, we need our own communities on our own instances, making it so that there are seven communities dedicated to the same team.
I’m a pretty old fashioned guy, I don’t really use the mobile apps, so I’m hoping for the backend update sooner rather than later, since I use the mlmym layout wherever available.
I have Connect on my phone but I don’t use it often.
