A quote from MTV,
"She does not Twitter or Facebook or anything,” was the response we got from reps for the real KStew when we approached them.
Here is a list and unless proven otherwise......
Poser List on Twitter
kristensss aka kstitch
kristenjstewart (and her myspace,facebook, etc..)
akaDaddyC (supposedly Peter, but go to his official Myspace, nothing about twitter is mentioned)
Rachelle Lefevre (no word on confirmation, but I highly doubt it's her)
Oh there are more, but I don't have the patience to play witch hunt..
Remember, if it has not come out officially or they haven't confirmed it....They're fake..
**addendum**The girls at Spunk-Ransom confirmed that the RobPattinson Myspace is fake as well via Rob's assistant, Nick Frenkel
it seems that one was missing from the list(don't know how that happened.....) it has be re-added.
