Something can be flagged (or downvoted) because people think the topic or discussion is off-charter or incorrect, or to suppress information/discussion for ulterior reasons. In some forums, tactics like flaming, disinformation, off-topic noise like jokes, upvoting diversions, etc. can also suppress information/discussion.
