Anyhow, legally, they can't do shit bitcoin is not regulated. Morons, all of them. Even their support staff is a bunch of retards who are probably scammers too. 
Their supports are very bad and slow in dealing things, most of the time theynever understand your issue and you will need to explain it to them several times. I could post about their support staff's bad service countless times however there is no way you could call someone a scammer unless you have a solid proof that they were indeed scamming.
Keep in mind that just because someone takes a loan and doesn't repay it does NOT make them a scammer. To classify as a scam, you have to prove that they had malicious intent when doing so.
