Shouldn't give your info out to ANYONE.
Every time you log on or change zones there is a message telling you, "do not give your email/password to anyone".
It's against tos I believe and there are numerous threads on forums from others foolish enough to give their info to others having their account hijacked. You made the problem now you want STS to fix it? lol.
PS. Everyone please stop crying hack when you do this...it's not a hack, it was your foolishness. A hack implies they cracked your account, not that you gave them your info..
