Why have my articles been unpublished?
Your articles may be unpublished for rules violations, but they are still available to you in My Account. Sometimes, if we notice a pattern of violations, all of your articles may be unpublished at once. Once you bring your content into compliance with our policies, you can resubmit them for publication individually.
Your articles may also not be published if they do not meet the minimum quality standards required to be Featured. To see if this is the case, open your article while logged in. There should be an alert in the Author Center at the top of the article notifying you that your article is not published because it currently rests below HubPages threshold for quality. You can rectify this by improving it and once again submitting it to the Quality Assessment Process.
