I remember having to fight a mod for him to restore a reply penned by Mike Pall, to a LuaJIT question.

Mike Pall is the author of LuaJIT.

The reply had been either deleted or edited to the point of being wrong (memory is foggy), because Mike Pall wasn't an expert at SO, and had somehow not used the site exactly as intended. The mod was very dismissive and patronizing.

I was going through some answers on a stackoverflow thread, and noticed that every single one had been edited by the same guy, just.. adding his own personal opinions and 'corrections' to them, and in the process making them universally worse and less correct

The idea that answers should be editable, and the gamification of stackoverflow, was an absolutely terrible combination
