I had a friend who was reproved and had not heard from the elders for over a year. The CO visit was a week away and they hurried up and had a meeting and gave him back all of his privileges.
I've seen this EXACT thing happen before. The Judicial Committee ends with reproof and promises from the elders that they will work to help the person rebuild spiritually through service arrangements, shepherding calls, etc. These promises are followed by complete radio silence for a year, then....WHAMMO!...the person miraculously gets all their privileges back the week before the CO's visit. The last time I saw this happen, the person had been approached by one of the elders (on his committee no less!) who expressed how much he missed hearing his comments at the meetings. When he responded that he missed having the privilege of commenting, the elder gave this puzzled look, followed by a flash of realization across his face. At the next meeting they pulled him aside and let him know he had gotten all his privileges back.
My experience is that 60-70% of elders are actually pretty cool, work hard, sacrifice a lot to serve the congregation, try to do the right thing, and aren't uptight about a lot of stuff. 10-15% of elders are obnoxious ego maniacs, and 10-15% are so clueless and out of step that they don't know the names of half the publishers and might not be able to tell you what book is even being studied at the Congregation Bible Study.
Of course what tends to happen is that certain congregations will often "breed" like-minded elders. That can be great when they're laid back and reasonable, but a complete nightmare when they act like a bunch of self-righteous, entitled, dictatorial d-bags.
