Report: Twitter hasn't aggressively filtered white nationalist content because it could affect GOP politicians

Here's how it works: Twitter increasingly relies on machine learning and algorithms to moderate millions of posts. When Twitter implemented a content filter for ISIS content, other innocuous content, such as Arabic speaking broadcasters, was also flagged by the system. Placing an equally aggressive automated content filter to target white nationalist content could impact the posts of some GOP politicians.

What they're saying: Twitter told Motherboard these claims are not an "accurate characterization of our policies or enforcement—on any level."
