the merit system is used to avoid spam,
and also teaches members to try to make posts that are useful and have value in every writing that is made,
if the post you make has value and benefits then you will automatically get merit from the seniors,
but if you don't get it even though you have made a post, then you should try to evaluate what your writing lacks.
I hope this helps.
To get merit, we must make a new topic? or just make useful reply in other people topic? thank you.
