I think there is a serious need for putting some kind of leash on the behavior of some of the moderators. Please remember that readers and participants are your customers and customers are always right. The success and failure of this forum will be dictated by readers and participants. I have seen time after time that some of the moderators behaving in an arrogant and abrasive manner. A reader or participant can be arrogant on occasion but not a moderator. They should be judged to a higher standard.
The role of a moderator is to moderate and not to take sides and get into debate or discussion. I find it very amusing that how they stay in hibernation mode. Then suddenly one of them wakes up, deletes few posts, bans one or two members, gets into a heated discussion with a member, shows arrogance, threaten to ban him or her and then goes back in to hibernation mode.
I hope you would look into the matter and set some kind of guidelines for them.
