I got super frustrated with Mastodon because of this. I've tried a couple of instances with no luck. And hilariously, I have to think that the furry folks are either having the same problem finding a home, or they are stalking me, because everywhere I move, shortly after, a ton of furries appear and do introductions. Furry stuff is not my thing, but I can appreciate how they might have a hard time finding a good place to settle.
