lol, i just asked this too: https://kbin.social/m/kbinMeta/t/114012/Inactive-Magazine-Owners

and now a mag i had already blocked appears in my sidebar as an explicit image, so it wasn’t a page reload bug either.

Blocking a magazine does not keep it from appearing on your sidebar random thread/post feed. I blocked an NSFW mag and reloaded the page and it was still present.

Or just block mags/bins/communities you don’t care about. Just got rid of one today and now I won’t see it on my all feed again.
