This is like a half-joke to me than a sarcasm. This contains half-truth -- based on the current statistics, Meta board is one of the boards that has high rate of giving merits.
Let me tell you my experience. When the merit system was introduced, members used to shower merits on post related to merits. There was a thread from a new member praising the merit system and it got above 50 merit points from 15-20 members in just few hours.
The situation is changed now. Members have realized the some are making these posts with the intention of getting merits only. So, it will not work now, some may put you on their ignore list though.
