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?
It’s hard to say. I use a keyword block that auto-blocks any community with “meme” in its title. So it could be dozens, or even hundreds. I’ve never counted. I have similar keywords for things I’m not interested in like “waifu”, “anime”, and most stuff adjacent to those topics.
