It's somewhat off-topic for the article, but I'm curious as to why you retain images uploaded for analysis after the analysis is completed?
After all, surely 99% of uploaders don't hold the copyright for the image they're uploading, so retaining them is on shaky legal grounds to begin with, if you're the kind of person who wants to be in strict compliance with the law - and at the same time, it forces you and your moderators to handle child porn several times a day (not a job I'd envy) and you say you risk a felony conviction.
Wouldn't it be far simpler, and less legally risky, if you didn't retain the images?
