Shitposters should be eliminated totally out of the forum.
See people who come to this forum to do only bounties and airdrops are always looked down upon as the bottomfeeder shitposter squad.
It's one of the good, amazing effects of merit system on forum users, particularly shitposters. Some of them have changed, and will keep changing to adapt to the merit system in positively directions.
Now if they eually contribute to discussions and they also do some bounties, it shows that they are not some beggar sort of shitposter and in the long run will able to earn some merits if they make quality posts.
Life is unfair for everyone. Each person has his/her own starting point, background (merit points in the case of bitcointalk forum members); but over long period of time, they can reach to the same targets if they tried to do it. Just set up your targets, work hard, you will reach to your targets someday.
Its not a question of being fair or not. In my opinion it is unfair and this is a good thing for the forum.
