Personally I like sex work and amateur tattooing better when they aren't part of some convoluted attempt at rationalist virtue signalling on social media. Honestly it's kind of weird that you landed on disapproval of promiscuity as the reason anyone here would find the happy couple sneerable.
Not strictly related to the OP but fuck kink-washing sfba rationalism, at the very least the attempted normalization of non-con sex play in a subculture as inundated with cult dynamics as them should be fair game.
The guy goes by the handle RatOrthodox, calls rationalism his religion in the replies, seems kind of a cult-brained ideologue anyway based on his other tattoos, and went out of his way to make boinking aella into a public achievement/trophy thing.
This is just from the OP, I bet I could find any number of additional absolutely ridiculous things about him if I bothered with his twitter feed (edit: someone else did). Basically he seems like sneer incarnate, and if rationalists ever stormed the capitol building I bet he'd be the one with the face paint and the horned fur hat giving interviews.
Virtue signaling is not really interchangeable with attention whoring, it's when you specifically (and usually clumsily) want people to notice that you are part of an ingroup, and in this case the ingroup definitely isn't just people who like amateur tattooing and horny post on main.
Maybe I should explicitly note that unless this turns out to be another aella publicity stunt she does seem pretty incidental to the whole thing and her only fault appears to be being attractive this type of weirdo in the first place, which I'm not blaming her for.
