After Zelda publicly quit social media, Twitter's VP of trust and safety, Del Harvey, said the company would not tolerate such abuse and is the process of updating its security policies. Right now, a person has to report a user and then their account might be suspended, but by that point, the damage is done. And, as Shirley Li at The Wire points out, there's nothing to stop users from creating another profile (and another and another). "It's not a minor nuisance," she says, "it's harassment."
None of this would be tolerated in real life, and the fact that it's online makes it harder to escape. Li suggests social networks look to gaming communities like League of Legends, which assembled a group of behavior experts (psychologists, computer scientists, and neuroscientists) to implement changes that reduce harassment among users. The results included the option to turn of the chat function, and something similar could work for Twitter — allowing users the option to stop replies or DMs.
But, what most social media platforms really need to do is stay ahead of the trolls, to stop bullying before it starts. Because when most people quit Twitter, they do so in silence. (The Wire)
