This sounds a lot like opening a flag for having opinions. Not getting along with certain forum members does not make a person 'high risk'.
As for the loan request, he was clear as to what he was doing.
Yes, it's my opinion that he's high risk, and it's my opinion that he was clear about his request. He posted in the lending board, not in the currency exchange board. He asked to take a "'loan', if you can call it that," not a purchase with an optional full refund. Which mean's he'll buy your bitcoin if the price goes up, but borrow it from you if the price goes down. That's not a loan, that's a scam.
Feel free to disagree.
