I feel the reputations are used poorly. I gotten bad rating from people who didn't "like" my posts rather than anything about "abusive" posts. Sometimes I received comments, but mostly I don't and the reputation ratings are usually anonymous so I cannot tell who gave them to me. Therefore, comments should be categorized and traceable so I can understand why and/or bring this to a moderator for correction. Perhaps have a reference # number.
Also, you should time out the reputations. I received reputation ratings 3 days and beyond from the original posting date. This is ridiculous. Usually, the thread has died, yet I am still getting a hit on my post.
