I'm not calling you a scammer, but standing up to them is not good either. There are plenty of threads about MPOE and their other businesses in Scam Accusations thread, including this one:
https://bitcointalk.org/index.php?topic=216280.0Raising awareness towards shady business is something everyone should be doing - and it's what I'm doing here now.
And don't tell me to leave, this is not a moderated thread and everyone is allowed to write in it. I do think that my business here is done however.
From that thread: "MPEX - Despite the fact that the security never actually stole or scammed members the owner Mircea Popescu is a disgusting person that uses the term "nigger" on his blog while also constantly putting people down and generally being a complete snob. Lied multiple times about being the owner of a successful company, if it wasn't for Satoshidice releasing stock in MPEX this person would be selling potatoes somewhere in Romania."
So ... MPEX is a scam because you don't like the guy running it? That is some dumb reasoning there.
