@malte I’m assuming you don’t want it to wait for some review process, but rather collect live feedback.
This might be a legitimate use case for a “just throw a blockchain-ish thing at it” solution.
Basically, a distributed event log of pseudonymized claims that can be synchronized on a whim. Can be additionally weighted locally based on private reactions to resulting classifications.
Abusable, but could be resistant to hostile takeover.
PS: I’m probably wrong!
