Some competitors are accused of scamming, its hard or impossible to bring any real proof for the users that they really were scammed, screenshots can be faked for example. Im solving this by having a "Anonymizer Guarantee", its a PGP signed message with the Deposit address and Destination addresses all signed by my PGP key. The idea is that this can later be used as proof, the PGP message can be posted by the user here and everyone can verify that the PGP signature is correct (signed by me) and check the Deposit and Destination addresses to see if the coins has been delivered or not. So if i would scam it would be game over immediately because there is real proof of it happening.
