Sharpshooter. Probable scammer.
This goxbtc thing is a scam epidemic...
@tagada: As you've pointed out 3 alleged scammers, could you provide some details how they try to trick you?
Any tricks specific to the use case on hand (GoxBTC <-> FreeBTC)?
Usually it goes like that the scammer tries to lure you into sending first, I would think real btc first of all. And then you're out of luck. So never send real btc first, and use escrow, or only send as small amount as you can afford to lose, and check rep. If in doubt - do not trade.
