@sashin @AnarchoNinaWrites We tried blocklists, then shitty folks got control of some of them. This is not a one-off; it happened on Twitter too. Still, there may be some value in them.
I'd be tempted to look at what works now, and change the software to make it easier. Say, build in a registry recording which admins blocked what for why, and a federated sideband channel for admins to talk to each other.
