This is what the brain does, too. All inductive reasoning comes down to statistical correlations. The human brain has NEVER had "robustness".
No it's not, just ask any advertiser.

If the only data someone has about an image is its colour balance and you asked them to classify which they think are pornographic, then yes you can.
It's a pretty stupid idea to impose such limitations though, on humans or ANNs. Even if you did only care about colour balance, you don't need an ANN to tell you that; just scale the image down to 1 pixel x 1 pixel, then look at its colour.
One of the great things about humans is that they can consider the context of a remark, although apparently this is not universal.
Not quite the color balance, but how anyone can assert the brain is hard to exploit is beyond me.

As others have pointed out, the complete opposite is true.
Good to know you know what our brain does, science hasn't figured out yet but you have...
