I think merit system is a good one in principle. But I have noticed that in some threads there are trolls and spammers, who use vulgar and offensive speech towards other participants.

They insult everyone who dares to have a different viewpoint than they express. So there is no true discussion possible, as they dominate on the thread and every normal person just quits participating, since it is not possible due to that kind of ongoing trolling.

What makes me wonder is that they have very high merit. How is that possible? Do they give merit to each other??

Anyway, I think it would be necessary, that the forum had better control about annoying behavior of some persons.
This control is needed to compliment the merit system.
Would it be possible, admins?
