its 1st time i ever see a hero member selling a sr member account anyways i still dont recommend to sale your 300 days old account for a cheap price or even for a not cheap price as long as this is not your main business here.
He is selling a bought account so there's no problem for him. It's not cheap anyway. Nobody can sell seniors for 0.40
BTC these days.
BTW I'm willing to serve free escrow if you want.
