Welcome to all the new users fleeing twitter! It's important to remember that the Fediverse (the correct term to describe what people frequently call "Mastodon") isn't Twitter and there are different social rules here. In order to avoid upsetting people who've been here for a while already, here's some guidance:

1. Become ungovernable
2. No snitching
3. Otherwise, do whatever the fuck you want

Hope that helps!
