This weekly Alternative Social Media update – the first of 2025! – is about getting caught back up with some things that have happened in the past month. First up, I’ll relate the latest changes at Meta to a specific interest of mine, Threads’s fediverse blocklist. Then, I’ll point you to a very fascinating back-and-forth discussion about Bluesky’s ATProto and ActivityPub (as well as OCapN). Finally, I’ll let you know the latest in ActivityPub Trust and Safety.
