In other words, this article is mostly grasping at threads here. It's good content, but the reference points it uses are laughable.
I'm not understanding. The article is grasping at threads because several of these incidents happened to be involving Call of Duty and Xbox Live? Toxic individuals are going to use any medium and any excuse they can to harass someone; they're not going to stick to conventional methods.
The point is that people are harassing game devs over the most innocuous stuff, which is exactly why Black Ops 2 was highlighted in the article.
