Maybe no one was taking how serious he needed merits so those multiple threads all saying the same thing was his way of showing it.

Granted, it may seem as if it's hard getting merits to your posts but I don't think being desperate will do anything for your case, rather being consistent by posting helpful content. Instead of focusing on how to 'mine' merits, why not take your mind off of being in a haste to rank up so you can enjoy your time here.
