I think he's an example of someone who had invested a lot of time into Reddit. He used Reddit like it was literally his job. Building up his karma like anyone else would grow their income. And then one day he said something quite unpopular. He lost a ton of the karma he had spent so much time building, and he snapped. He continued getting downvoted more and more and he eventually stopped caring. Eventually he mutated into a horrific troll with the sole intention of destroying Reddit for other people, and the malice behind his intentions gets shuffled up in confusion as he manipulates other mods into believing it is beneficial to the subs to keep him as a mod. I actually have zero real knowledge of the situation, which most people really don't either and is probably why he is so successful in the little game he has been playing.
