Something similar happened the last time when I received 10 merits for one post. Merit system was totally new at that time. Well, maybe sMerits decays after 2-3 days or so.
I have a feeling that you're lying about sMerits since so many members explained very clearly that sMerits didn't decayed at the moment. You're always saying the same story again and again. Don't know what is your intentions and feeled like you just want to continue this thread without any valid reason. I think it is better, if you can locked this thread and read the thread very carefully what other members said repeatedly.
