I wouldn't take that as an accusation of abuse of merit by merit source, but sometimes it's also not the best way to spend some of the merit he has. krogothmanhattan sends 1 merit per user post regardless of whether they like it or not about his business. 90% of the merit recipients are users of good repute who may have been involved in many successful trades on this forum before.
So if you're asking if it's abuse of merit then I think you still need to review the goodwill of krogothmanhattan who sent the service to any user who replies before March 4th.
I will PM him a link to it so that he can say something if he feels like doing that.
krogothmanhattan seems to be aware of the existence of this thread, he started posting 1 merit for some users above even though he didn't say anything.
