I just see you are open minded to receive correction gently way, no body and nothing is perfect and to open my mind that learning will never stop. In case of merit, I see it as way to improve this forum by reducing spam and increasing quality post simultaneously. As I heard from some members, it works even there are some impacts that is not expected such as merit trading, etc. So to improve such merit rewarding, the merit senders should be selected carefully not only by their judging to a post but also their integrity. I don't whether accepting merit senders need psychological test or not, but at least their responsibility should maintained in the beginning of the appointment as merit senders.
That is good idea as I heard for reducing impact of merit, merit has shown good progress for spam reducing and encouraging member to post in high quality. Now some threads talk about the impact, by more tight selection and encourage the integrity of merit senders then the negative impact of merit system could be pushed out. I am thinking other way to add your idea as perhaps it will not easy to evaluate integrity in this forum by make transparent of merit senders and evaluate them by pooling. The top one for a month to be allowed more smerit and the bottom one to be reduced the smerit numbers. Perhaps this is the fair way for each merit senders and merit receivers in this forum to be evaluated, the result is forum improvement.
