Perfect business trick.
Nefario was given scammer tag, coz he didn't payback the bitcoins & assets in GLBSE.
Now he sent double payments & ordered to return the bitcoins, which makes whoever received the bitcoins & not giving it back has to get scammer tag.
How many persons will be given scammer tag in this forum for not paying back the double payment?
@Theymos: what you going to do about this?
There is no trick. Nefario holds the records of my asset ownership. He sends that to the issuer and me, I send him back any overpayment. Since your honesty is above reproach, you act as escrow, o.k.? Passes your morality test?
