That's a about as dirty as a scammer can get. If he's selling it, and then taking a loan to abandon, he's getting paid twice for the same account.
Putting a monetary value on accounts seems very difficult to me. It's not something I apply to my evaluations when deciding whether to fund a loan or not. Instead, I try to evaluate how much the user values his account. I hope it's a practical strategy, only time will tell.
I'm not an expert but I think Hero account with a legendary potential merit is worth more than 0.015 BTC.
How did that account get 1000 airdropped merit with only Hero member activity? Are activity points lost if you purge posts from a single two-week period of time?
If the person has the activity more than 750 on the airdrop time I think received 100 merits. For legendary then there was no fixed activity but it was 750 or more. So as there was 750+ activity they received 1000 merit on airdrop.
