Cheating User Retaliates with Negative Feedback

I have run dozens of forum post jobs as well as other jobs. While the vast majority of dpf users have been great. Unfortunately there is always a bad apple. I caught a user cheating and while most would walk away, this user decides to retaliate with negative feedback. It's bade enough I have negative feedback from an old user that couldn't deliver, now I have to accept negative feedback from a new user who was clearly in the wrong. I don't agree with this and feel the user should be banned and the negative feedback should be removed. I've already provided undeniable proof.
