And btw, it seems like the 100 merits you have was airdropped I didn’t really check but if you take you time to go through the forum read old threads and also new ones that are being created, look at how those that re earning high amount of merits do their post and what type of posts get them merits you’ll be able to earn some for yourself.
The 100 merits you're referring to was from early days before the merit system was implemented. Old accounts got a default amount of merit based on their current ranking that time.
