But what happens to the genuine newbies who sign up to share their ideas on that forum? Who doesn't care about the merit system
True beginners will be recognized by the effort they put into sharing ideas and trying to gain knowledge. They will have no trouble getting merits or even rankings as I'm sure some of them currently have higher merit than activity.
Even though they didn't directly state that they cared about the merit system, in reality they were users who cared. I would say they don't care about the merit system if the newbie just join for the money and the activity is just for the bounty. We can get to know him more closely, so that in fact beginners who want to gain knowledge and contribute to the forum by sharing ideas are those who care about all systems in this forum, including the merit system.
