seen much stranger than what you just laid out, and much more often than I would have liked to. You are absolutely correct that some dudes attract the crazies. I am one such dude. I figured it out though when I was a sophomore, because I was accused of sexual harassment and sexual assault in the space of about 3 months. I was lucky enough that literally nobody but a couple of teachers in my school bought it, so even though I was ashamed to show my face, people came out of the woodwork to reassure me they knew it was all BS.
I actually ended up having to tell people to leave one of the girls alone b/c anytime she stood within 10 feet of a dude, there was a pack of girls who would say something like, "Watch out dude, she'll sue ya!" BUT I learned from it. I learned to identify those girls and never encourage or engage in flirtation or anything, and NEVER to be alone with them in a room. This dude, at a minimum, exhibited very poor judgment in where he went and how he responded to these girls.
