I am very glad to say that after the merit system this forum become more unique and competitive for its users.I am strongly agree with your thoughts that how merit system changes the culture of this forum .Now only those users survive who have some valuable thought to forward for this forum all other spammer eventually dead.The most important step that was taken by the moderator is a demerit system that breaks the backbone of spammer.As most of spammer here are newbies (spammbies) makes there first thirty activity to become Jr member for doing signatures.
