I'm wondering if a globally accessible "silence list" would be good for !gnusocial - it would:
1. Let nodes interchange silence lists ("I trust the judgement of site X to only silence those who'd be silenced here as well")
2. Make it more obvious for remote users (that aren't admins) who have trouble reaching other nodes if they are blocked of if there's just a bug.

Are there any downsides (privacy, easier for spambots...) to this idea?
