OMG, I'm a newbie and I've just found out 'bout 'trading' merit.
but, my question is.. are there any rules and punishment 'bout it? can it cause an account to be banned?
Some senior members gave negative trust to members involved in abuse of merit system (awarding merit points to low quality posts). No one was banned though. It is hard to find the buying and selling of merit points especially if someone is buying 1-2 merit points from multiple accounts. If you notice such threads in other forums, you can report here.
