On the first page there is lots of people with red trust inquiring about this. I never said you had them actually being serious about giving you an offer but I was just warning you and hoping that you would not sell to ANYONE with scam or a possibility of scamming.
I do not selling to red trust scammers, but they can create new clear account anytime. I do not check buyer post history, just reviewing trust history if there looks something fishy, but unless trusted members give user negative feedback and make the user red trust scammer, it is not easy to judge because anybody can post negative feedback for whatever reason.
And anybody can turn to be scammer, even the most trusted users, for example TradeFortress, or just TF. So everyone has the possibility to be scammer.
If you ask whether I mark the account I sell to a buyer who turns out to be scammer later. My answer is no, because my accounts can be resold (and they are), so I have no idea who the sold accounts later belongs to.
