Confirmed scam on one person, below is my conversation with him.

Please ban all 3 aliases, hopefully the money he stole wasn't worth the two months of posts his main account had.
Also, please note that all 3 accounts have left feedback for each other.
I'd also examine all of Loker's feedback for more aliases, specifically Gigadice. Obvious review format is obvious.
