I think it's totally justified to leave a negative trust it's been known for the accounts to be sold and then later use that reputation to scam. I think people selling accounts with positive trust are the ones to really look out for though.
And this is exactly what op has done.
I repeat again, this is a question for clearing to every bitcointalk users that trading their accounts is legal or illegal and do not concern mine in anyway!
You sure about that. I remember you being caught and reported for farming a load of accounts in the 777 giveaway thread using bots a while back. Looking at them now many look to have negative feedback and have been shilling for crapcoin ICOs:

So, are you the scammer or are you just selling accounts to them? And no, it's not against the rules to sell accounts, but this is exactly why it's frowned upon.
All those accounts got hacked, I don't control them. By the way I didn't use them in anything illegal
