I just went trough your post history, and yes, it's perfectly possible nobody gave you a merit for those posts... I mean, you're not giving new information, no posts that required extra effort,... in most of your posts you're just agreeing with others, or you're bringing points that have been discussed dozens of times already.

Also, there is no need to only count merited posts, your merit count is clearly visible... If you stop posting to get merit, but just start being a member of the community by asking real questions that have anything to do with crypto currency's, by helping others or by actually providing new insights into a discussion, you'll get some merit sooner or later
