Seems like a good use for MechanicalTurk (mturk.com), at least until a free/open-source API becomes available that can replicate the abilities of a human.

I'd recommend sending new photos to a queue, and only letting them get indexed after someone from mturk has marked them as acceptable.

If the workers find something illegal, seek counsel and do as the counsel advises.

Definitely not!!! Asking people to look at child porn for you is a terrible idea, and may be illegal in many places.

You're not asking them to look at anything that you've identified as illegal material. If you already knew it was illegal, you'd have deleted it or reported it yourself.

You're asking them to moderate unknown material from new users you know nothing about. That's something that every volunteer moderator from Reddit does.

There were paid staffers doing that at MySpace back in the day. I talked to their head of security; not a fun job.

thats pretty much exactly how it works though
