> I probably have cursed myself by checking these people's profiles after the fact
I think you really did. I don't watch much YouTube and don't use social media beside Instagram—which I mostly use for messaging friends and not exchanging photos—but I don't see a lot of erotic content on the mainstream platforms.

I wouldn't call it Erotic. It's hard to describe but you just know that it's somehow sexualised. I would think that somehow maybe I am a crazy prude but these profiles then do link to adult content (from their youtube via link aggregators, which is definitely not an 'adult content' platform). I think it's some form of cross platform advertising while skirting around the 'no adult content' rules of youtube.
