I keep seeing images that fall under my blacklists when browsing the 'Popular' tab. Is that supposed to happen? Is there a way to make them be hidden instead?

Blacklists should work there, I just tested it.

I just tried it and it doesn't show the typical "blacklisted" image, it just removes it from the list (only for you).

Maybe you're being too specific with your blacklists, or the images that should be blacklisted were mistagged.

Looked into it more and I guess it was the 'quick toggle' thing, seems to work now
