Does these posts deserve to get 20+ merits? I guess not. But each merit sources have their own way to give their sMerit.
I still remember some merit sources were give a lot merit in a single post or few posts because they don't want to waste their time to merit each post for 1-5 merits, so it's like a short cut.
However the good thing is, he meriting the users who are have a lot merits e.g. above 1000, so even they're already have 10K merits, they're still in legendary rank as there's no higher rank than legendary. Although some campaign managers nowadays are giving more incentive for 2000+ merits and so on.
To be honest, it's not clear to me if you're just messing around here
To make it clear I guess he wanted to say if qwk misusing his sMerit.
