Let me know if this has already been suggested or discussed and I will lock the thread immediately.

We all know that a very large number of spam in every section of the forum comes from users below Member rank, and the reason for that is mainly because they are participating in Signature Campaigns and they need to reach the threshold offered by the campaign to get their payment.
To reduce that, I suggest that any user, below Member rank, should be restricted from posting outsite the Bounties (Altcoins) sections if they are wearing a signature. They can still post freely in any section they want if they are not wearing a signature on them.
This would not bother any user with a low rank but constructive thoughts as they can still share their opinions with the community without any problem, and if they want to join a signature campaign, they will have to earn at least 10 Merits to reach Member rank and then they can wear a signature and post constructively to get paid for it.

Let me know your thoughts on this.
