Not a bad idea. Chaos engineering.

I wonder if there’s a way to crowdsource relay trust status. e.g. if you find an event on a relay that has an invalid signature, you broadcast a kind to all your relays that indicates that this relay can’t be trusted. People or clients who deem your pubkey as trustworthy can make a determination of if they want to stop subscribing to that bad relay. Basically as a mechanism to not need to perform as many verifications of signatures on events as it could be expensive on computation and battery if you’re on a smartphone.
