Not every merit sent is an abused, especially when it's not a source merit.
From what I can tell, almost every of the posted quoted above were deemed to be merit worthy by more than one user(4 posts merited by 9 different users) how is that by any means an abuse ?
Well, let's see what the admins say about that. My job is to report when i see something "not ok" or fishy, the rest is up to the admins.
Merits transaction isn't moderated, and admins don't give a shit about how users decide to spend their sMerits, however, Theymos might be slightly concerned, so it's best you send him a PM with you claim, who knows ? He might agree with you.
