You're complaining about being scammed by someone with negative trust who is involved in account farming and trading?
It's like going to a gang chop shop to buy a car and complaining that the police arrested you for driving a stolen car. Oh, those dirty scammers, I wanted a cheap car so much!
This is not a valid analogy.
You think? I bet I could find people in this thread who think otherwise

Accounts and trading are not forbidden by the rules. Consequently, they are not banned and the topics are not closed. This is a gray area.
I find this to be a red area, red, like the trust of that seller and one that you'd get on that bought account sooner or later.
I understand that. But scam is no longer a gray area. Such people need to be banned and topics closed.
I have a similar opinion about both, buyers and sellers. Especially the ones trading in trusted accounts.
