From /cow/ that summed it up said:Brianna was first came to GamerGate's attention when he admitted to making a sockpuppet account "BroLolz" to pose as a GGer and make them look bad. After that he made a horrendous meme which GGer's quickly hijacked, using the meme to mock her and point out her hypocrisy (she used an image of a screaming spastic Asian boy to represent GGers, making fun of spastic minorities is kind of a nono with SJWs.)
After that, GG started looking into who he was. He'd opened an independent video game studio with $200,000 given to him by his parents, which he spent quite a bit of getting a sex change. The game he made was of course, utter shit.
As soon as people started mocking how terrible the game was, a new twitter account was made with a name similar to "chatterwhiteman" who suddenly had Brianna's dox and made a slew of over the top death threats.
It's been pointed out that Brianna's "harasser" posted messages with his same speech patterns (particularly using the word asshat a lot, as Brianna does) but it was enough for him to claim he felt thread and flee his house, and then go on interviews with every major network but Fox, in each disheveled with crazy hair.
That is until he did an interview on David Pakman. David Pakman is about as far left as it gets, but he is a damn good objective journalist, and tried to actually investigate the issue, so he asked Brianna a couple simple questions, specifically "How do you know the person who threatened you is part of GamerGate?" "How can you attribute this person's threats to all of GamerGate?" and "Why did you choose to publicize your threats?" He claimed this was a hit piece, and has subsequently not done any interviews.
Of note though, the attention whores collectively referred to as Mojo Jojo briefly got into a slapfight over which of them was most harassed. Brianna asserted based on a newsweek article he was (despite the article saying over 90% of the tweets weren't harassment) Zoe immediately took issue and said she was the most harassed. Anita meanwhile posted a tweet declaring herself the most harassed.
At the same time, other female attention whores were quite angry Anita got to go on Colbert, notably Suey Park (of #CancelColbert infamy) who asserted she got to go on because she was white.
Brianna has since lost all credibility and been largely ignored by both sides.
