It seems I could not post as a comment on campus so here is what was meant to be a comment on the earlier thread:
Lucy's comment caught my eye and reminded me of how damaging a frape can be.
A flat mate of mine had his relationship ruined by a frape. The initial false posting was on his (then) long-term girlfriends' wall. asking her to marry him. He had no such intentions. She thought that it was a genuine question and answered positively. Once it was established that it had been a frape, both parties knew that the other had entirely different ideas about the future of their relationship, and it soon broke down.
Whilst typing this I was reflecting the meaning of the term 'Frape' i.e 'Facebook Rape.' I wont go into the psychoanalysis details but to tell the truth I don't think that the phrase is all that hyperbolic.
