@Lexialex There are a few. I don't know who octodon.social has or hasn't blocked, so I can't speak to your odds of encountering a regular person vs troll garbage.
(for anyone not knowing why we are wary of such things:
@Lexialex It depends. If you see somebody with an anime avatar whose home instance is gs.smuglo.li or libertarian.club, then they're probably an asshole. People with anime avatars from witches.town or octodon.social are more likely to be OK people.
@CobaltVelvet doesn't put up with assholes on her own site.
Octodon is a nice general purpose instance.
