What happens if a badly-run server allows bullying, spam or other nastiness? What if it refuses to respond to abuse reports? In such cases, other servers' admins can use their ultimate weapon: defederation. Defederation cuts off all communication between the admin's server and the abusive server, and the worst-run servers end up extremely isolated because so many servers have defederated them. This is why it's always worth telling your server admin if there is bad stuff going on. #FediTips
