In fact, they changed how the Flamebate E-Peen is given because of Klan forums.

On the past, what would give you the E-Peen would be your total number of posts. So people would simply spam threads in their klan forum for the sole purpose of getting the E-Peen and, as you already know, you’d never get caught unless someone reported the behavior.

So, to not need to remove post count from klan forums, they changed the method to the current one, and made that only count for public posts.
