I've run a game, granted only one, and I'm still in favor of it. This is probably because I'm a prolific poster - both alive and dead.
Honestly how many times before MBP started playing was this really a problem? I know the reasons for putting the "Jav" rule into effect, but I've been playing a long time and I can only remember a few - and one of those was a special revealing a scan before the night ended - only to find out he had been killed during the same night.
We are all pretty good with regulating ourselves, and I don't think we should be punished for the bad judgement of 1 player who isn't even with us anymore.
If some sort of ban was put into effect, I probably wouldn't check back with the game as often as I do now post-death.
