I'm not saying these tests are totally useless.
They're also easy to fake. If this became widely adopted, you could hire someone on Fiverr to boost your score.

The point to note is that there is (usually) a job on the line, and a programming challenge is not the only part of the screening process -- it will usually be followed by a live coding session/interview. So the question is would someone risk gaming the process, when the chance of getting caught is high. We think not.
