Probably OP wants to introduce another sub merit system for their local board allowing only good users to post on their section. The discretion and the decision to allow good users to post will be managed by the moderators on that board. The moderator/admin will set a sub merit system to allow only users that reach the least certain amount of merit to be qualified to join in the local board. This may be a good idea because spamming in their local section will be reduced.

Yet, if post is to be reduced on local board then probably the shit poster will then return to spam on Super Mega Thread section. The problem could be solve on local board but the problem will go overboard on other section especially the SMT.

Besides, suggesting for a sub merit system in the local boards will limit only to higher ranks or to those who are qualified to post in the local boards and the newbies with great and brilliant minds will be limited to this. Probably this will create another problem on OP suggestion.

As the legend says since we had a lot of differences here in the forum due to our culture and values it may be good to follow what the forum has offered. We should adapt how the admin run the forum instead of complaining and suggesting an idea that will only allow to create another form of problem. So, I must say to follow the forum, respect begets, and love the users here instead of complaining. LOL
