Really, all that should matter to you is whether the OP/buyer will compensate you in the (apparently rate) case that a charge-back DOES happen.
The link you posted simply proves my point and does absolutely nothing to support yours. (I would go as far as to say that it's entirely unrelated and a non-sequitur in regards to your previous argument.) That list just shows what people with ads up on LBC are willing to pay for MoneyPaks. In other words, those ads are the opposite of OP's and the bad rates simply show how common fraud and chargebacks are. It basically shows that people are able to get MoneyPaks for such low prices (due to fraud?) that they're willing to sell them for anonymous currencies at artificially high rates.
Actually, there are other concerns that are not monetary when transacting with a user like this. These are funds of unknown origin and if they are from illegal activity or scammed (which many MoneyPaks are), people trading with him could get in trouble. Good luck explaining yourself when you've loaded $10K in MoneyPaks on prepaid cards under your name - I guarantee you you'll end up like Charlie Shrem. Meanwhile, prophetmopic will he sipping a pina colada on the beach in Hawaii, because he's doing everything under Tor + socks5 and is anonymous.
Anybody not doing due diligence before transacting with a user like this is naive, likely immature, and foolish. Judging by your own activity here, I just described you perfectly.
Regardless, I'm fairly certain prophetmopic can speak for himself. He has been here for a month and a half and has transacted a large amount, so I'm sure he has already considered his answers to questions like these. This has been the elephant in the room since this service began.
Edit: You can always just message me privately if you don't want to say anything publicly. Other people's security is not my responsibility, so it doesn't really matter to me whether or not you go into further detail publicly.
