@mergerson We can't prevent racists from making instances and we can't prevent them from being racist on their own instances. Maybe we can enable people to avoid racist instances but how? Many people who say "I'm not racist" are pretty racist.
@elsantonegro @mergerson Most instances are in the US and Europe, so is not surprising if popular ones are racist, because those cultures are fairly racist.
@radehi @mergerson Its tough. Due to the federation model, you really need to trust that your admins are on top of things (blocking racist instances, having good moderation, etc.)
The disheartening thing about the recent incidents is that they occurred on the biggest (most popular) instances. You would hope that they'd be ready for the influx of diverse users from Twitter. Obviously, they were not.
