YES!
I have seen a Site that had Great Potential turn into one of the Nastiest Sites I have ever used.
I mean I never once deactivated myself from SH *came close once* but because of all the Problems the ANONYMOUS USERS have caused and continue to cause my Friends I have left Amirite and my many Friends.
Seriously I take a lot to reach BREAKING POINT but wishing one of my Closest Friends HAPPY CANCER , that was it :(
