In order to avoid this, what would you think of having a “new joiners” instance, where
- hexbear, lemmygrad and ml would be defederated
- politics and news communities would be blocked at the instance level
I could see the first point being almost the default for topic-specific instances (along with not allowing NSFW material). Who wants to join a D&D, MTG, Star Wars, instance only to run headfirst into a Stalinist troll? With the caveat that I don't see them that much unless Russia gets a mention in !uk_politics@feddit.uk.
I am unsure if the latter is needed - give people the option to subscribe or block politics, shitposts and memes. Perhaps start with the default to "Local" and have an introduction thread about it. However, I may be a statistical outlier as I default to "Local" and rarely use "All" and so don't run into things I am not signed up for.
