To be honest, I don't participate in SO that much. The problems with close votes, and the HN community's dislike of the situation is well known. There is no easy fix for the situation, although I do agree something should be done.
The core of the issue, as was pointed out above, is the vtc-please culture in certain chat rooms. Culture is a very hard thing to change (impossible?), and whatever change you make to how closing works is unlikely to be effective unless cultural change is brought about too.
