On mastodon you’re just an account on someone else’s server (except for the extreme minority that run their own server). On urbit every user is also their own ‘server’ - there’s no distinction between account and server. Infra nodes just do public key lookups and route encrypted traffic. As far as abuse risk - you have to design the system to be resilient to it. People behave based on the incentives the design allows. That’s why the web and other federated systems centralize. Urbit is explicitly designed to fix these underlying issues.
