Ten years ago, a group of white dudes baked the DNA of the platform without thought to harassment or abuse. They built the platform with the best of intentions. I still believe this. But they were ignorant to their own blind spots. As we all are. This is the value of diverse teams by the way. When you’re building a tool with a global reach (and who isn’t these days) your team needs to look like the world it’s trying to reach. And ten years later, the abuse has proven too much to fix.
