You are following the right advice, sadly, I have been a victim of that too, but it has been since last year. I'm sorry to hear that you are too going through with this. I agree with everyone here. Report this person...I had to do that for a person who was stalking my fiance and I since Texas. So yeah we feel your pain...I'm on Facebook, but I have no choice on the real name thing, my family is also on there and that's how we talk, since we never seem to catch each other on the phone.
I relied on my friends who cleared me of it, I was not sure who was posing as a friend or not, generally people who knew me were willing to listen and realize what was going on. Then they spread the word to some of my other friends. I was a little upset that some of it is still going on. My fiance has gotten a few e-mails and also some IMs from people he didn't know.
Since was came back from Texas, things did get steadily worse, I didn't want we have the rumors fixed, yeah...same problem as you...I'm so sorry to hear that it s happening to you too. No one deserves this.
