Merit abuse is happening here for sure and currently most of the members are posting cases where merits are sent in bulk. Members sending 1 or 2 merits to their alt accounts are playing smart and hard to spot.
That has probably happened on this forum people who greed in merit to be rank up even it is really prohibited they do cheating here.
Just keep on posting maybe merit source will give you if they spot you good quality post.
Cheaters are always there, even though in online games or anywhere cheaters always exist. Hopefully, theymos find a way on this that merit system that he implemented not getting abused.
