The harassment campaign is largely fictional and just used to try and gain points. There was a literal FBI investigation into gamergate and they found no actionable evidence of threats or harassment.
Here's an example of what we're dealing with here:
August 27th 2014,
Anita Sarkeesian tweets a picture of some alleged harassment she received from an egg account. Note the absence of the gamergate hashtag and the obsession with blood drinking - this is probably a response to Anita's recent (at the time) criticisms of twilight.
October 30th, 2017, NBC News uses these tweets in their insane propaganda video
How Gamers Are Facilitating The Rise Of The Alt-Right - except they photoshopped #gamergate onto them. The tweets were made before the hashtag was even coined. Straight up fabricated evidence from a national news network.
This is just the most recent example and we're lucky that there is clear evidence here. There's an avalanche of false attacks that are given main stream attention. Hell even in this example, look at the quasi flattering tone of some of the tweets - even odds that it's a false flag.
The thing is if you run a news story about a real person and accuse them of doing stuff they didn't do, they can sue you. But if it's not a real person, there's no legal danger. So if you see a news story where there's no use of the word "allegedly" or "according to soandso" and they're just reciting a story as fact, it's probably fake.
