Motivation
As a user I want to be able to scan images for potential child abuse content so that the harmful material can be identified.
Acceptance criteria:
- We are able to manually trigger a scan using php run.php ./extensions/MediaModeration/maintenance/ModerateExistingFiles.php
- An error rate of less than 1% for images that are processed via the maintenance script
- Images are checked against PhotoDNA
- If suspicious content is found an email is sent to autoflaggedcontent@wikimedia.org
