@nprofile1q... @nprofile1q... To use a physical metaphor, we've built technologies that allow anyone in the world to walk into our house and sit at our kitchen table.
Blocklists ban the people completely AFTER they've behaved badly. Shared blocklists let us tell neighbors not to let them in.
In real, human communities, relationships are more complex than binary accept/deny lists. We rely on reputation, relationships, and word-of-mouth referrals.
Perhaps we could model those aspects here, too.
