regarding other sex pests at RT, i dont think blaine would be one. he's got no commitments, and all he has to do to smash is swipe right. he rode the company bikes for sure, but i'm skeptical he dove into underage fan muff when he's got plenty choice already.
both ryan/adam are like average joes with commitments. both lost weight and have that acceptable "dad" bod that out of shape fangirls go crazy over cause it hits their daddy issues. people like chris (kerry too) seem too awkward and not attractive enough to initiate anything. if they did, they'd probably wuss out before it got to the stage of boning a fan.
i'd cast my eye over someone like miles - dude looks fine, has enough 'star power' for rwby fangirls to go mental over him. after the cuck situation with arryn and after their breakup, i could see him seeking out some mediocre looking fans who worship the ground he walks on to achieve his dream of a threesome.
geoff bounced back pretty good with the emily chick, worst thing he's doing is getting pegged and apologising for the patriarchy. same with jack - caiti's a 10 compared to him and any fangirl. chubby fangirls would have to actually find jack attractive in the first place for anything to take place too. assuming caiti isn't the only person on earth who finds jack attractive sexually (we're not even sure that's true), i think any potential 'victim' would have been happy to come out a lot sooner about the ugly fat dude preying on them, compared to the relatively in shape middle aged man who fits in with their daddy issues.
