I'm up to 92 so far. A mix of non English, furry and hentai porn, and a few I just don't see the point of. I've got 6 or 7 users to, mostly bots that repost reddit content, and the piped link bot.
Lemmy.world blocked exploding heads at the instance level, so I don't need to worry about them thankfully. Before they were blocked by our admin I had pretty much every community of theirs I saw blocked.
