AI systems can't distinguish between a person and a program that has been designed to create clickstreams that people would create. This is (among other reasons) why the click fraud problem is so difficult.

When I say AI, I mean a system designed to track trends and derive needed conclusions. This can never be 100% accurate but certainly can filter a good percentage.
