I will suggest that people will only give a limited number of merit to a particular member within a time frame. Example: Member A can give Member B lets say only 1 merit within a period of two weeks. So it means that Member A cannot dump 10 merits at once to Member B. Member B can receive merit from other members but once within a time frame like once every two weeks.
If done this way, administrators will not be able to offer merit to a person who has 2 quality posts within 2 weeks
