A disputed flag is whenever your flag was dismissed as neither helpful or declined, someone reviewed your flag but no conclusive action was taken. It happens in some situations:
- An edit on a post in the Low Quality Review Queue, will resolve the flags attached to it as disputed.
- When a post, flagged as NAA or VLQ, enters on the Low Quality Review Queue while being upvoted or accepted, if all reviewers selected "recommend deletion" it will result in a disputed flag.
- If a post with offensive or spam flags is rolled back or undeleted and the flag dismissed by a moderator.
Disputed flags are considered neither helpful nor declined, regardless of the action taken in response to them.
