The first step towards removing spammers from this forum should be to stop the accounts buying and selling.Because newbies buying a Sr.Member account would surely spam because they dont have that knowledge and experience and secondly they are buying account only to earn through signature campaigns,meaning just to spam to increase post count.
So account farming should be strictly prohibited first of all,so that would stop users by creating alt accounts just to sell them in future and stop newbies to spam with Sr.member or hero member accounts.
