Flagging a comment tells a site moderator that a comment requires moderator attention. On most sites you can flag a comment by clicking its flag icon or link.
Flagging a comment is only counted once per person; you won't need to do it multiple times.
Proper Flagging Guidelines
Every site has a different commenting policy, be sure to review it before flagging comments.
Generally, comments should be flagged for:
Violating a site's commenting policy
Being clearly unrelated
Attacking other commenters personally
Generally, comments should not be flagged for:
Disagreeing with the content
Disputing with other commenters
**Moderators may be able to see if specific users are abusing the flagging function
Report Spam to Disqus
We also appreciate reports of any spam comments you find. After flagging a comment for the moderator, feel free to click on their profile and flag the user.
