Banned for suspicious behaviour?

Now my account was just banned for something that i don't really understand, i was making a deal with a guy for my account. Now we were supposed to use Shredderbeam for the MM and he sent me a PM for confirmation (thinking now it was probably requested by these two guys attempting to scam me). Now the "Shredderbeam" who came into our msn chat was using the email "[email protected]" and as that address is not the same as it is in the MM list I became suspicious about this. I asked him for the explanation and he said it was his new msn because someone was impersonating him. Now only minutes later i got banned from the forums and i pulled the plug on the deal. I can also provide msn logs of the conversation.

My user that was banned was "mehike".

 

Actually, it was I who was in the conversation. I PMed you, and you left. THEN you were banned.
