My preferred way to browse here is using All and blocking communities I don’t want to see. That way I get exposed to new things I wouldn’t seek out on my own (for example: British archaeology)
I accidentally blocked a community while trying to block a user and when I went to unblock it, I saw I had 1250 communities filtered. If I had to guess, 90% are either porn, sports, or anime.
What about you?
Zero. Every time I’ve been on the verge of blocking a community (or instance, since kbin can do that) it winds up vanishing anyway.
