Comments have some built-in security measures to prevent issues such as spam, abusive comments, or private information from being posted for all to see. Public commenters must pass the robot test, and all comments go into a moderation queue, and only editors can approve comments.
SPAM, ReCAPTCHA, or the Robot Test
Spam is mostly a concern with comments on publicly accessible knowledge bases. To combat spam, we've added ReCAPTCHA when folks who are not logged in comment. Most of your commenters will be able to comment by clicking a box confirming they are, in fact, not a robot. If ReCAPTCHA notices anything fishy, the commenter will have to perform an additional task that robots would have a difficult time performing but are fairly straightforward for humans. Honestly, some of them are actually fun!

All comments must be moderated. Submitted comments will go into a list under Reporting > Comments.
Only editors can approve or delete comments. Writers will be able to view but not moderate comments.
