A) I would confront my friend, I've actually got a mate who is like this goes round stalking on Facebook adding everyones girl mates to chat to them. Pisses me off at times because I get girls messaging me saying "who is this creep" when they see I'm his only mutual friend. I tell him that hes creeped her, I tell him to stop upsetting her and to back off.

I've considered removing him off Facebook but considering hes someone I see with friends on an almost daily basis I've so far not because of the hassle. If he continues and really upsets someone then I might say to him I'm removing you because you keep upsetting girls I know and it needs to stop.

B) I would have just left her to it.
