The first post I viewed (I’m brand spanking new) had an awful troll comment. It was quickly removed, but it was mentioned they’d made comments on six different post before being banned. What protects the community from an instance that let’s anyone join? Hope this was the correct place to post.
If a lot of bad actors seem to originate from a single instance that instance will end up de-federated (unlinked) from the rest of the community, isolating them. It will be a slowish process so be sure to engage with mods in your communities if you see bad actors, especially during this boom period.
good advice
