I think that this can be trivially solved by openAI. they could store all their responses and then for a fee allow schools/professors to submit the answers they're getting from students like they already do with turnitin if the answer is 90% the same... easy to deduct that it's not original. plus, because OpenAI makes you login, if it is a match they could allow you see the email address associated with the submission... if its the student's name, pretty obvious that it was not their own work.
