The bottom line is that you have to make decent posts. They need to at least be well thought out, relate to the discussion, and have good grammar. The one sentence posts you've been making are not going to get merit. It doesn't have to be perfect English, but people need to be able to understand what you're saying. If English isn't your native language, go to your local boards.
Avoid posting in the altcoin discussion section, or in any megathreads for that matter. There's a lot of spam there, and even if you were to make a good post (which is doubtful, considering your post history), it would get buried by other crappy posts.
Don't beg for merits, or pm people asking for merits or anything like that. Also don't buy merits.
And don't make a thread about merits in Meta.
I mean, a lot of it just boils down to "read the rules and don't be dumb". I guess that's hard for some people though...
