This could actually be a veiled way of sending merits to yourself. Given a good post, few would question the use of sMerit upon it.
However, this would only be to "new" account farmers rather than older ones since they would just as well post on their higher-ranked accounts and rank them up.
Perhaps it's a new wave of accounts being farmed as the max monthly merit cap is reached?
Abusers will always try to abuse everything they come across if they can. There are numbers of new accounts those are trying to make seriousgood posts and they do not have any alts
Me for example

But for me, i still don't know. Can we have 2 or more account?
