I would also bet that when the landscape decentralizes there will be a lot more cp, revenge and peep-videos and other illegal shit in the mix that will get through through the cracks since massive established sites had to actually fear shutdown and losing all revenue unless they had robust gatekeeping mechanisms.

There are technical solutions for p2p sharing with moderation. Not to prevent bad people from sharing their stuff, but to keep spaces clean for those who don’t want to see it.

This is also true for communication, which is why Fediverse is not good enough. Hosted servers should be an optional part of the infrastructure, and the data (users, communities, posts …) shouldn’t be connected to them. Like with torrents you can host a torrent tracker, and you can host a BTDHT node, and you can automatically download and seed rare torrents, and none of this is connected to whatever people hosting major trackers decide.

NOSTR gets that part right, but the user experience its authors imagine is not for me.
