First time i hear about it, but will never use for sure. This activity is prohibited by Paypal TOS, and i wouldn't risk my paypal account just for doing an exchange. So if you use this, your account is at risk. Sure people can say, but i receive payments without problem ect, but soon or later they will change their version. No matter if the personn behind this service basically want to make "legit" transaction. Fact is Paypal + Money exchange or Bitcoin = NO
