Assuming you have already searched for this kind of discussions and did not find any?
You are right though! There were two-three other threads mentioning "Boring Topics" and "Redundant and Spamming Users". I could have replied underneath them however I didn't find them relating to my specific point which is a solution about changing the system(merits, forbidding thread openings, etc.) all over. They were talking about reporting and banning users. I thought my idea deserved a new thread.
This one is really close to my thoughts:

All of these people got at least one reply from someone like you sir "You are actually doing the same game." But unfortunately that doesn't contribute to solving the problem.
