He's (/was) a Gawker network journalist who prided himself in doxxing violentacrerz (va) on reddit. VA was responsible for moding a few of the NSFW and unsavory subs, one of them being jailbait, on reddit. Agree or disagree with the sub, it's crappy to dox someone and go after their job/family/income etc. Then again bluelisting is the goal of SJWs these days.
He's also got a few other not so thrilling things that he's participated in as well... but I'll let you read the wikipedia article.
There's plenty of scummy things he's done. The one that sticks out in my mind is when he faked cancer on reddit to try and make some stupid point about sexism, it never panned out. Just angered a lot of people who lent their sympathy.
He's just a trash journalist and I'm not going to give him any more clicks than he already baits people into.
