Have you already tried to contact the moderation center?
What is moderation center?
Based from The Pharmacist's comment, buying accounts encourages/leads to scams, spams and account farming. It's a fact. That's the whole reason you were tagged. It's a just trust rating since DT members are fighting spam and account sales in the forum.
I also fight with scammers and spammers.
If forum rules allow you to buy and sell account, and you do that in official way, in my opinion enough is left
neutral information about that in trust section. I don't see reason to
punish someone because i don't like some forum rules.
This is even more strange for me, because before or right after this transaction I talked about it with a moderator and staff member (if i good remember with Lauda) and nobody have problem with that.
Do you think that leaving red trust in situation like this is necessary punishment or private fanabery/abuse of power?
