You could use a "OTP" to provide this: give out tokens ("OTP"), anyone with that token can submit, keep a record of the user (eg github username, email address) and token, run a bot to delete submissions that don't have a valid token, check the token+user pair, if there is a mismatch blacklist the user that token was given to whilst removing the PR.

If only there were a simple way to make tokens that weren't fungible and could be given to others
