The only time I have been scammed was via PayPal (not ASR related).
The scammer was using a stolen identity, I even managed to talk with the real owner of that identity. Yes, they knew that someone was using their identity in paypal, no, there is nothing they can do about it, and they didn't care too much about it either, just that from time to time someone would call them very angry.
PayPal on their side was "you wanted to avoid paying our fees, well, that's your problem, next time pay"
My take is that everyone has his share of responsibility here, PayPal for facilitating a way for scammers to scam people if they don't receive their fees (at the end of the day this is positive for them, people start to use it because it is free, and end up paying because they have been scammed. If there was no fraud, nobody would pay), me for trying to outsmart the system (there is no such thing as a service to send money anywhere for free) and the scammer, well, for obvious reasons...
