I suspect most of them sit on lemmygrad. This is the beauty of instances and federation - nuance! Some users might be assholes on some instance communities, but if they're not maintained in a way people are happy with, they can splinter off and make a better place. For instance, Beehaw can maintain a gaming community which is set up to be safe and avoid bullshit gamergate stuff, and they can call it "Gaming" because it's not the only instance that can host one of those.

The issue with default subs and subs with obvious names on Reddit is that they build a certain personality and approach, foster certain views or don't moderate well, and then new people come in and amplify that because that's how they've seen the interaction working before. In that case, the best you can do is make a secondary one that has more strict rules - /r/truegaming, /r/games etc etc - which are difficult to grow because they're unlinked. Being on beehaw means it's part of the beehaw umbrella, so has to abide by the rules of the instance. Kind of a neat system.
