A post whose source is a direct link to a Deviantart image without the associated deviation ID included within it. These are considered bad links because there's often no way to find the original Deviantart page without that ID in the link, however most current Deviantart URLs will contain this hash.
If you see this warning while uploading, make sure to change the direct image link in the source field to the Deviantart post where you found the image.
