In all past bug bounty programs I started I made it clear we would only prioritize findings as serious if PGP encrypted to the security team PGP key to review offline.

The serious researchers all knew how to do this and complied and usually got paid, and the unencrypted stuff was basically always noise we never paid out on.

Probably not as much of a filter now that AI is in play though.

That kind of stuff won't work anywhere near as well as a bullshit filter anymore: Most of the bullshit is AI generated and AI has no problem following rules like that-- even better than humans.

Instead, you'll need something like "you must enroll your pgp fingerprint in our system by sending a handwritten postcard featuring a tourist attraction in your region".
