Jesus Christ. Let's tackle a few of these.
Goldberg created alts that spouted ridiculous arguments he would later cite on his main account, the one he attached his name to, as "crazy SJWs". Those other accounts were to create strawmen for his real account, again, the one using his real name, to attack.
Your LMGTFY link points to one college student nobody's heard of making a false rape threat and links to articles claiming Anita Sarkeesian never reported threats to authorities. Here's a citation.
Short story: Asshole MRAs (and GamerGate supports) call the SFPD, and the person who answered claimed to not know of any reports made by Sarkeesian. Turns out the SFPD immediately passed that info along to the FBI from the beginning. Even Milo, Gamergate's ""intellectual leader"", admits that.
But the narrative that Sarkeesian made up the threats is too useful to admit is wrong, so the original articles stay without noting that further investigation proved them wholly incorrect. Then people like you reference them, hoping that readers won't dig deeper.
Any time someone makes threats against one of the people Gamergate hates, they blame third-party trolls. Conveniently, these trolls magically disappear when threats are made against Gamergate events. Gamergaters love to ignore the fact that an infamous 8chan troll took credit for the threats. 8channers love going after "SJWs", but they fuck with Gamergaters on occasion as well. Because of lulz or whatever.
It's sad that Slashdot is taking these conspiracy whinings so seriously, but I'd encourage people to do some research. To date, Gamergate has accomplished nothing aside from calling their enemies whales and trannies while claiming the mainstream media is out to get them. Perhaps it's not surprising that they're hailing Breitbart Tech, yes, that Breitbart, as a savior of tech journalism.
