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 filesize and MD5 hash are the same, then change the source field to the new source, and remove the bad id tag(s). The MD5 hash can be compared with http://onlinemd5.com/ or https://md5file.com/calculator. Note: A source is legitimate only if it's hosted by the original artist.
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 and tag the original upload with the duplicate tag.
