User:B-bot/source/No longer orphaned checker
< User:B-bot | source
This task will loop though the dated Category:Orphaned non-free use Wikipedia files category that is due to be deleted tomorrow. For each image in the category, it will purge the image and purge any articles for which there is a fair use rationale. If it finds the image to be no longer orphaned, it will remove the {{di-orphaned fair use}} tag.
