When right-wing trolls and outright racists get kicked off of Twitter, they often move to Gab, a right-wing Twitter competitor. Gab was founded by Donald Trump supporter Andrew Torba, who says it’s devoted to unfettered free expression online. This week, Andrew Anglin, editor of the neo-Nazi site Daily Stormer, became an active Gab user after a succession of Internet companies refused service to his website, forcing it offline. The site also hosts controversial right-wing trolls like Milo Yiannopoulos and Andrew “weev” Auernheimer.

On Thursday, Gab said that Google had banned its Android app from the Google Play Store for violating Google’s ban on hate speech.

Google’s e-mail doesn’t explain how Gab violated Google’s rules, and the company’s policy on the topic isn’t very specific. It says only that “We don’t allow apps that advocate against groups of people based on their race or ethnic origin, religion, disability, gender, age, nationality, veteran status, sexual orientation, or gender identity.”
