why i am got less merit
Though I can barely make out what you're trying to say, I think you're wondering why it is you haven't earned any merit. The answer, to me, is as plain as day. You are trying to write posts in a language that you don't know, and the only reason you're doing it is to get paid. Because you don't have a good grasp of English, everything you write here is going to sound simple-brained and uninteresting.
Look at this post:
I really agree with your topic that is so good and I have done it to my friend and finally my friend has earned income through this forum.
This is a generic, 3rd world shitpost written by someone who is only incentivized to post in English because he's paid to spam. The post is sloppy and in broken English and not worth reading (or writing). You and your ilk need to stop doing shit like this--that's what the merit system is for. The idiots just haven't caught on that they won't be advancing in rank yet.
