Yeah, most instances are SFW content only, so the porn is mostly on a few specific instances which may or may not be federated with yours. I’ve come across 3 different instances with communities I need to block for being porn : / even with nsfw hidden on mine I still see the blurred posts and that’s not really much better… especially having to go into the community to block it…
I’d like to block the whole instances, especially after coming across a post asking where non-consensual stuff can be posted…
