Idea: Crowdsourcing muting of scammy/spammy users. Muting is a public event, so if some scambot writes me, I can mute them. But if I mute someone, my close friends probably want to mute them too.

Sort of "mutesync" would make our lives much nicer here.

Of course, I would carefully choose people whose mutes I follow, because some people are just drama queens and mute is their final act.
