lot of people will do fake reviews and shit just to stay in that section. And of course this would open up another avenue for people who wants to earn money by doing fake reviews, aside from people selling merits and post this thing would be the worst as they will be making shit up for other people to believe in that project.
when the merit system starts some people thought the system will collapse with, selling merits. but it is not, the merit system works very well. the people holding smerit don't spend for useless posts and for money(only few people). someone can give only one or two fake reviews no more they will be caught.
