It's worth seeing how gamergate describes itself. The "what is gamergate" column on the sidebar of a subreddit where they hang out might help there. Do note that I do provide the hyperlink, but I do not endorse either front.
Those posts are almost exclusively about media bias, manipulation and censorship. Isn't that what GamerGate claims to be about?
In the top ten, precisely one item (number ten) is about video games.
GamerGate is about more than video games, it's about media manipulation and bias and it's about journalists acting like activists.
Also if I recall correctly Rotten Tomatoes removed the ability to submit a review for a movie that hasn't been released yet, which to my mind seems like an entirely sensible restriction, particularly in the face of the obvious spamming that was going on. It seems to me like RT made a product decision relating to what best serves their users. What's the argument against it?
This is silly. They locked out reviews being placed before the movie was released in theaters, because the rating was being deliberately bombed towards the single digits by people who can't possibly have seen the movie.
Does that review sound like someone who is upset with a movie studio because they created fake outrage, or someone who is upset about a movie's female lead?
