I use your addresses. My wallet is empty, and is not indended to receive anything. Money go directly to you.
What this service does is looking at transactions (as they are all public), and when payment to your address arrives - it sends reg. info.
You can test it, by the way, by sending money to yourself (buying your own item). As you receive 100% of what you have sent, it is safe
P.S. And don't compare it with PayPal
At least, we don't ask for a scan of your passport
