A post that is no longer available from the source link. Usually this is because the work was deleted by the artist.
Compare with bad source, where the link does not point to the original image, and bad link, where the source is correct but it leads to a direct image instead of a proper post.
Guidelines
If another source for the image is found, follow these instructions:
If the filesizes are different and the image is inferior, then just ignore it and do not upload it.
If the filesizes are different and the image is superior, then upload it if you consider the image worthy, then parent the original to the upload (by clicking edit on the child post and pasting in the parent ID in the parent field) and then tag the original upload with the duplicate tag.
