What is a disputed flag?
There are a few posts that I flag, and they get disputed. Then a little bit later the post gets closed. Why do my flags show up as disputed if the post got closed?
Moderators don't dispute flags; other users with 10k reputation do. When a flag is disputed, it is considered invalid and does not have any effect on your ability to flag, nor can a moderator do anything to validate it again, even if it was valid to begin with.
