On version 0.19 you can block instances so that you don’t see any posts from that instance, instead of having to block communities one by one, you still see comments from users of that instance in other posts so it isn’t completely blocking the instance.
“I won’t be happy until I stop seeing posts!”
I treat this place as reverse reddit. You can’t browse by subscribed because then you see 4 posts. But it’s hard to find the communities I might like. So I browse by all and block things I don’t want to see like foreign language, tentacle porn and Linux communities. That way I still see new communities I might like and get an endless scroll.
