My daughter is having trouble with an anonymous person harassing her over yahoo messenger and myspace. We are almost certain we know who it is, but I want to be sure before I do anything about it. I was told from some guys at work that I could find out their IP Addresses and therefore see their names (or parent's names) and locations and stuff. Is that true? And if so, how would I go about doing it? Or is there a way to somehow see that two different myspace profiles are coming from the same IP Address?? Thanks for your help!!
