Benkbeny, the rules have not assured any member merits, if it was to be like that the administrator would have made it an automatic process on their own criteria to merits posts when they are good, but that is not how it works, member's have to give you merits, and they are not assured to give them to you, if you create good post, you stand a chance of them giving some to you, but there is no assurance of that.
Why did you have to worry, people may have been reading your posts, but they didn't believe it deserved their merits, you do not have to worry because of that, attracting merits on a post does not mean people suddenly read your posts after not reading it for long, it means the meriter thought the posts deseved their merits and gave you some for it.
