@babab each server has its own community rules. Home.social (this server) has its guidelines and info here https://home.social/about. Its guiding principle is the same as Bill & Ted’s - be excellent to one another. FWIW each server also maintains its own list of which other servers will be federated to it so can block that content from being picked up.
