In my profile, in flags history. What it means when you flag an answer or a question and the flag has the state disputed?
Check out this conversation on Meta Stack Overflow:
A disputed flag is a flag that was issued on a post that then received an "invalid flag" flag from a 10K+ user. Both the original flag and the flag used to mark it as invalid will be listed as "disputed" in the respective user's flagging summary. Once a flag has been disputed, its state will not be changed by any additional action on the post.
