I saw your post history and I will enumerate where most of your posts are:

1. Off - Topic section
2. Mega threads

Aside from that, most of your posts are one to two line which can be helpful I think (I didn't read it) but most of it are in the mega threads. Nobody will browse a thread which composes of more than 20 pages and see which of the posts are considered helpful. If you want to be merited, don't post on mega threads.

It would really be up to that person if he really wants you to have a merit, Well many in the community tend to give merit to people that are very helpful with the topic that has content, A substantial post is needed so you can be merited by someone, Well I can say that most of your post is in one liner or two, It is very blur to really get the support from other people because most merits end up decaying and never been given to anyone.

I recall seeing 2-3 threads where few senior members were giving merits away - anyone with decent quality and constructive posting history could apply and get rewarded.

Other than that, don't hope to get merited for 1-sentence posts in spam/mega threads. Hardly anyone reads such posts anyway. Try to do something useful. You claim to speak 4 languages, how about posting some useful translation to local boards (ie. forum rules, or explanation of how forum ranks work etc). There should be at least 1 merit source in every local board, so likely you'll get merited.

You must have a good quality post to have merit and specially it will be helpful into the community, post must be constructive and not a spammy one many people gave merit if they see that you are deserving to have that merit but many people also are afraid to give merit because they are thinking that they are going to link with each other.

well that is not true because you can't tell that the forum moderators knows everyone here each an everyone knows there selves, in summaries what i
 trying to say is that you only post meaningful post for you to be upgraded from newbies or from jr.menber to member.. secondly the hero and legendary gives merit to what create a difference to the forum or what is impactful.

Your post is supposed to not belongs here, but i will answer it anyway.
To get merit you must make someone who has sMerit love your post and they will give some to you.
As simple as that, even if you make a really good post but people don't like it, people will not giving any sMerit

We can not claim merit as a matter of right.  Our function is try to do justice to our job.  Increase our knowledge.  You very well mentioned about quality posts.
I think everybody is not  reading every post.  Likes and dislikes also differ from person to person.  It is possible you post  some quality post  but the same is not  read by the person who likes these views and is convinced by your statement so because of not reading how he can give you merit.
On the other hand; someone may not agree with your statement but reads it; so he will not be convinced by it.  

So under both the circumstances you may not get merit.  because luck also play a role.

So I advise just try to do good certainly you will have some good; time may be short or long.  
Edit
After posting this reply i saw 4 merits to my account though in the evening it were 3; so I got one today.  Say congratulations to me  
Likewise you will get it too.

Making a quality post, by constructing a useful post, is simply signifies to the topic related and meaningful to others, marit can be transferred, to enable upgrading in next rank level...

You must have a good quality post to have merit and specially it will be helpful into the community, post must be constructive and not a spammy. so for me that's the only way you will get merited.

Well, you have a point. But the principle for merit still holds that unless you make quality posts before you can get merited. This merit issue is becoming concerns for many but its been said that Do not post threads about merit because that wont fetch you any. Instead of raising this issue, I would rather advice you use it to post something useful.
