To be honest, I just don't like the idea of giving merits on local boards. I am sorry if I sound like a bad guy but I would say that local boards feel the national pride and duty to help each-other to rank up and give merits to their compatriots.
I think the situation is following: People from poor countries help each-other to rank up to participate in signature campaigns with high payroll. That's probably why I see that person only gets merits from local boards while his/her posts in English language never get rewarded. This isn't fair and probably destroys the main idea of merit system on this forum.
If I am wrong, correct me, no problem but this is just what I see and notice.
