Many users become overly focused on seeking and participating in bounty campaigns, often neglecting the time needed to understand how the forum works. Most of them continuously do it for even years, just like what you mentioned.
There are some money in bounties, yes, but I think it could only be possible for good projects, which  I assume, may be considered lucky to experience success. If you (newbies) wish to gain higher probability of getting merits and ranking up, then provide contents that are generally or specifically helpful to the board of your interest. Try following users here and observe how they create their posts.
