I do not know why some people just did not post high quality post but got so many merits and i got none.
It's because of posts like this, which are garbage:

I can't even see much of your other posts, because you must post in boards I have on ignore. My guess is that you haven't earned merit because your posts suck.
Also, you now have negative trust for trying to buy a bitcointalk account, so good luck with that.
It still amazes me how people don't see exactly why they're not getting merited. Doesn't "lisalise" realize that you can't just post shit like the above and expect people to give up something (merit) which basically has a worth of about $10 on the black market? It ain't going to happen, buddy.
