I can see 2 negative feedbacks on your profile for cheating bounty campaign referenced here- https://bitcointalk.org/index.php?topic=5383361.msg59113670#msg59113670
Are you not guilty according to this reference? If you haven't cheat, respond there and/or reach out to both member through DM who have sent you the negative feedback. There's no other way to get out of the feedback since they have used reference with enough proof.
