I just came across this thread after searching the Meta section for my name. Anyway, how can you say that I'm involved in cheating an auction? I bought the account at the BIN price because that seemed pretty cheap for a Member account.
But, yes, I have witnessed some users that bump up their sales thread and/or give false feedback to themselves with alt accounts because I have had experience buying one from a user that did so.
Please report the PM to me directly. Who is the alt account? Magicisme? If so he's already got negative for something.
And up to now, I have no idea what that "something" is.
