i think you took it wrong , they are not asking you for many posts .
they need quality posts / helpful posts to give you some merits which is also depend on person giving you merits .
also i saw your posts , they are one liner and below average post like any other bounty hunter , and some of them are just bounty reports .
so if you really want merits then work hard , invest more time in forum and help others . also now if i said that posts are one liner , it does not mean you will write 10-15 lines posts , bcoz they prefer quality post in compare to lengthy posts .
apart from this i also want to share one thing me too noticed merits are too hard to earn , so i think admin should appoint more merit sources .
thank you for your suggestions, i better understand now about quality posts i will try more to get those merit
