"the main purpose of the merit system is to encourage those who are contributing to the forum by posting good posts." - it is just not working, it is clear forum admin fault. Spammers/bad quality posts are present in all active forums.
If the forum admins have failed, then why are you here in this forum?
I think every forum or organization has its own rules and regulations that govern and control them, and anyone who seems uncomfortable with that should just leave and not try insulting the whole system.
This forum has been in existence for more than a decade now, and this merit system introduced in the forum has helped reduce spam and has kept this form moving in the right direction for a long time. Then who are you to abuse the entire forum policy, and what are your proofs for your claims?"
