Ohh, that makes sense, thanks for the tip. I'm on Memmy for iOS which doesn't seem to have it, but I'll check out other apps, would be nice to have one with this feature.
Instances can block other instances but not users from what I can tell. When I see something I be don't want to regularly see I go to that community and block it, like all of the popular porn communities that often float to the top.
Right, this is what I've been doing so far, it's just getting a bit annoying to keep blocking communities left and right lol. Really looking forward to the block instance feature.
You are right, you need to block individual communities from your non NSFW account. There are not many that pop up in the all feed, and they can be blocked quite fast.
