He admits it is his account.
Even if he could somehow argue that he "didn't" take those loans, he still deserves a negative rep for being an account seller. If he is willing to do it on btcpop, you can be sure he'd try it here.
That's actually very true. I wonder how easy he admitted it. He must have few more accounts in here. Who knows.
He is a bit wrong about his assumption though. Yes, the admins will not give a shit about it, the mods will not (may be) ban his account because scams are not moderated however I am sure if your evidences are satisfactory to the DT members then they will tag him. Here he is wrong, tag from DT members will not be good for him. Any lander will see the tag and they will deny his requests.
Good job OP
Update1
PS: Looking at his feedback page, it seems he actually repaid every loan he has taken from here. I am just confuse a bit however I will not trust him with my money.
Yep. His rep here, is still standing.
But it was like that on Btcpop, as well. He had repaid about 30 loans. (Most smaller, however). So he had a bit of rep. Built up the amounts, and then vanished.
he still deserves a negative rep for being an account seller.
What evidence did I miss about him being an account seller? I saw the PM you posted, and he said he let other people use his Btcpop account, but that's it. Sure as hell sounds fishy, but I'd like to hear what he has to say if he responds here. He's basically saying he doesn't recall borrowing money, that someone else used his account and did so. I'm not sure I buy that, and that PM sounds too confrontational for my liking given the circumstances.
On BTCPOP, there is a pretty thorough verification process. In order to be eligible to borrow, you have to verify your address through physical mail, upload your passport and drivers license, and take a selfie with a code, in order to prove your identity.
Third parties are strictly
not allowed to borrow using someone else's account, as that defeats the purpose of verification.
In this case, the only reason to allow another person to use your account on a lending site is to take out loans. Using his identity. I can't even imagine a reason for him to have allowed other users on that account (which he admitted) without him being paid for it. I'd love for him to address this point. I'll PM him with a link to this.
Now the big thing you have to know here, is that in order to withdraw BTC from aforementioned lending site, you have to accept the withdrawal via an emailed confirmation link. (Did not think of this until earlier today. Would have mentioned in opening remarks.)
So the person who took that loan out also has to have access to the original email address that Onnz423 signed up with.
So either he just shares all his accounts with his social group, or he is a liar.
