I'm sick of nsfwlemmy.com content popping up in my feed
For the most part it's borderline child porn or stable diffusion spam. There should be an option to opt out of content from specific instances on account level.
I want to discover content, since lemmy is young communities form constantly. Reddit /all has no communities that are marked nsfw. Intuitively I'd assume nsfw instances or communities are searchable but are hidden from /all.
