OP is making 2 points, one about merit
What merit? is it about seeking merit to rank up is classified as a merit hunter? that's really a big joke.
Many users were complained they didn't get merit etc, hence people create report unmerited good posts, report posts to merit source and another one thread for rank up. Then people who comment on these thread are judged as merit seeker lol.
and the other about bullying.
No one can control people who aggressive towards other users.
All I can see it's a subjective matter, which there's nothing need to take any action.
