Twitter never built in a way to deal with harassment because none of the people designing it had ever been harassed, so it didn’t come up. Twitter didn’t build in a way to deal with threats because none of the people designing it had ever gotten a death threat. It didn’t come up. Twitter didn’t build in a way to deal with stalking because no one on the team had ever been stalked. It didn’t come up. That’s not to say those things don’t happen to white boys. They do, but very rarely.
