There's a problem with this approach where GG is concerned though. This approach -- and why you use it -- is detailed in Gavin De Becker's series of "Fear" books, which discuss a wide range of personal security situations, including being on the receiving end of potentially dangerous harassment. In the situations he describes, the harasser is acting alone, and the reinforcement he or she gets for the behavior comes from the reaction of the victim. If there's no reaction, there's no reinforcement, and eventually the harasser gets bored and stops. This works pretty well for individual harassers/stalkers if they're not actually psychotic.
But when we're talking about a hate group, it's different. This is a situation that De Becker didn't cover in his books. It's different, because the hate group reinforces each other regardless of what action the victim takes. They share stories of what they did, compete to try and top each other to be the most "cool" in the group, and that sort of thing. You can see this dynamic operating plainly in those IRC channel logs I linked to in my last post -- the way the members urge each other on. At that point, the reinforcement comes from their buddies and stopping it by ignoring it no longer works. You couldn't stop the KKK from lynching you by ignoring them -- if they wanted to lynch you, they would lynch you. You can also see this dynamic in middle and high school -- if the bullies gang up, ignoring them isn't an option for their chosen victims. The mob will win. A solo bully you might outwit or outlast, but a group? No.
Similarly, ignoring GG would not have worked, not for the primary targets at least. (It might have worked for some of the secondary targets, possibly.) They would have continued to reinforce and egg each other on and their victims would have been left to suffer in silence with no one knowing what they were going through and damned little support.
When it's a reinforcing group that's behind the harassment, ignoring it just doesn't work. Exposing it and combating it directly by continuing to show and stress that this behavior is not going to ever become an accepted social norm, that they will never succeed in getting any legitimacy of any kind as long as they keep being vicious, that there will be unpleasant consequences for doing this kind of thing, is the only way to bring it to an end. GG will end when the cost of being associated with it becomes too high for the membership, basically. When they are blocked on Twitter, as is happening; when the only news stories written about them stress how awful they are, as is happening; when they come to realize what the people actually working in the industry they claim to love actually think of them and what they're doing, and how they'll never get a job in that industry if it comes out they associated with Gamergate and took part in its activities -- this is what will kill Gamergate, not silence from Gamergate's victims.
This is why, if you look on KiA, the talk is all about how "We're winning!" (BS), "The industry supports us, but they're afraid to say so!" (Total and complete BS), and so on. The /b/tards yanking the strings know that if their footsoldiers really get a grip on what this mess is costing them, that will be the end of it. And it will.
That's why silence would have been the wrong call here.
Edited to add: Another step in the right direction as
Patreon updates its guidelines to specifically deny its service to harassers, doxers, hate groups, coordinated fraud -- as well as people encouraging any of this kind of behavior.
