Doesn't there need to be a "report abuse" button on each image? Users could report it and only then would he use something like Microsoft's PhotoDNA (which an user mentioned above).

Only a qualified lawyer can say.

But then what? Look at positives, and decide? Or just forward all positives to LEA, let them decide, and nuke what they indicate? LEA probably wouldn't like that.

A user above mention Microsoft's PhotoDNA. He could run the flagged images through that first and if it returns nothing maybe look at it.

Or don't look at it until a certain number of users flag it but still run it through the PhotoDNA. Now I am curious how imgur handles this problem.

Or use all of those CP databases, and just report images flagged by some subset of them.

I am curious how this gets handled. Having been goatse'd a few times with CP, I cannot imagine reviewing that crap on a regular basis.
