Invalid Report: (Lemoncide)

The other day i traded a vintage lugermorph to "Lemoncide" just the other day the account that i had purchased was taken back and i was removed from his friends list. I posted a comment to ensure that the password hadn't been changed purposly and warned if the account wasn't handed back to me a report would be sent. A day after the comment was posted it was removed from (His/Her) wall.
