5) To all members who usually collect a lot of merits, kindly do not participate let others benefit from this and if possible see if you find any good post to merit or give them some tips to improve.
Thats the more reason why probably you should have put something like a merit restriction
Probably members who have earned X amount of merits should not bother participting,but instead take part in the giveaway if they feel obliged to
That would make things clearer in my opinion
