Account trading was not closely monitored prior to the implementation of the merit system. It seems that only account sellers were tagged by the Pharmicst. However, after the introduction of the merit system, account trading became widely tagged. This is because it has become increasingly difficult to build an account through merits alone, leading people to choose the option of purchasing accounts instead.
In my opinion, if those involved in account trading had proven themselves to be trustworthy before the merit system was implemented, it might have been considered to remove their tags. However, tagging them instead would have disrupted the balance of the forum and could have reignited conflicts.
Account trading should not be tolerated after the introduction of the merit system. A trustworthy individual would not engage in buying accounts and would instead focus on being a valuable contributor. Good contributors do not need to purchase accounts; they can easily build their own.
