A post whose source is a direct link to a Paheal image, rather than to the Paheal post containing the image. These are considered bad links because there's no way to find the original Paheal post from the image link.
If you see this warning while uploading, it means you should paste the link to the Paheal post on the upload page, not the image itself. Though consider checking for alternative sources first if possible, as Paheal posts are often third-party sources.
