It seems like he is only remorseful because he got caught. And as Cooper pointed out: he only mentions the negative impact on himself and his family (what about the girls whose photos he posted?) and tries to shift most of the responsibility to Reddit.
It's a weird fall from grace for violentacrez. Redditors, in general, loved what he did. His subreddits were hugely popular; /r/jailbait was once voted subreddit of the year by the community, and he himself was once moderator of the year. Now he has been unmasked he is facing the wrath of the wider population, which doesn't 'get' Internet humor, the tongue-in-cheek nature of trolling, will never admit to finding teen…
Reddit's employees never really loved the guy (AFAICT) but they tolerated him because he moderated and kept illegal content out of his subreddits and they sure as hell didn't want to touch any of that stuff.
Violentacrez turned on Reddit as soon as he was outed, looking for any scapegoat to take some of the pressure off of himself. All things considered, I'm not suprised that Reddit is not backing him up.
