@Gargron well I would politely suggest that standards of conduct and safety are going to mean more to people than interoperability over the next while.
Perhaps now is a good time to address how to make the out-of-the-box Mastodon experience one where people aren't exposed to white nationalists by default.
You have a chance to do something.
@Gargron more explicitly - Mastodon the company should start directly alerting people to which servers they REALLY need to think about blocking, and needs to do it at the install stage, and afterwards as routine.
