i thought nostr.band is already it, at least directionaly? tho I think there's a difference, what makes cuntanalysis a company is the "proprietary" data that they attach to it and then put people in prison based on 5years old leadked datbase downloaded from a darknet forum.

in nostr attribution already exits since we're all signing our own notes to prove they are ours. Tho maybe they find all my nyms?? xD
