Showing too much 'skin' detection in software

Question

I am building an ASP.NET web site where the users may upload photos of themselves. There could be thousands of photos uploaded every day. One thing my boss has asked a few time

Answer 1

I would say your answer lies in crowdsourcing the task. This almost always works and tends to scale very well.

It doesn't have to involve making some users into "admins" and coming up with different permissions - it can be as simple as to enable an "inappropriate" link near each image and keeping a count.
