Scammers are coming up with new ways everyday instead of just playing fair...
Here's another type of scam I've experienced on a different forum:
Scammers: Person A and Person B
Victim: Person C (looking to buy/sell/trade something)
Person A creates an email that is similar to a high ranked staff's name, could be exactly the same but making it @live.com or something like that.
Person B now contacts person C that he is interested in selling/buying/trading what person C wants to sell/buy/trade.
Person C will not trust Person B because he probably doesn't have much vouches, Person B says that he will get a trusted MM. Person B invites Person A, who is using an email similar to a name of a high rank staff on the forum and pretends to be them and the MM.
Person C trusts Person A, gives person A the details, money or whatever and Person A and B leaves when they get what they need and block Person C.
