This is something I was thinking about as a solution for traffic violations: have drivers rate each other; increase the "trustworthiness factor" of anyone who thumbs down few people and those people are also negatively rated by others and/or have accidents; decrease the multiplier for those who just negatively rate everybody and so on. Unfortunately, I think you can hit some mines related to https://en.wikipedia.org/wiki/Arrow%27s_impossibility_theorem https://en.wikipedia.org/wiki/Arrow%27s_impossibility_theore... but who knows? Maybe it won't happen given that you don't want a transitive relation, you want a numeric score for each driver. (Such a score could be used to influence insurance premiums; as an anarchist, I'm generally thinking about solutions for problems like "suppose we don't have patrol cops".)
