IT IS EXTREMELY UNSAFE BECAUSE THE MONEY CANNOT BE INSURED. The risker takes ALL the risk in this scam. There is zero chance the sender can PROVE the money ever arrives.
Yes, but you must choose
-> You are anonymous, and you buy your Bitcoins against cash

-> You make bank transfers on MTGOX or other exchange website and transactions are recorded and tracked

Personally I took the risk and I can say that this website is trustworthy! No scam!
