Yep. He creeped out several who did not appreciate his advances. He may not know how old they are, but that is even more reason to refrain from posting in that way. If I were you I would submit feedback. If enough people complain surely they will do something about it. I already put in a very lengthy complaint about him. If he approaches you tell him in no uncertain terms that you do NOT like him posting his personal photos and that his solicitations make you feel very unsafe and uncomfortable. It all needs to be put out there in case it ever comes into question.
