Wish I could say I'm surprised that "anarchists" are defending intellectual property in response to AI art. Technological conservatism seems to be the default left wing position these days.
The funny part is that if they want a fraction of the zero-sum financial benefits of IP without relying on government enforcement, they should support NFTs, which they also oppose for all the wrong reasons.
the correct way to do decentralized moderation:
anyone can offer to moderate for anyone else, and anyone can request others moderate for them.
moderation consists of tagging content in ways that are requested by the user of the moderation
the requesting user then can filter out posts, or not, based on the tags and who supplied them, in their client app
tagging can be done by hand if desired, and also by software, this is entirely up to the moderator
