I'm not based on the logic applied to beginners. After all, the other participants also received their titles only because it stayed longer on the forums and generally posts solid spam and trash.
The forum does not have much of a problem with higher ranks because they tend to produce less shit, and even if those that do are not really a problem because they are few. The problem is mostly about the many juniors created only to participate in campaigns. 100 junior in signatures are producing an average of 1500 post a week and there is no way of keeping a good moderation. Anyone
can could create them out of the blue and start messing up the forum.
If the admins do detect a problem with members or above, they would act in consequence.
