So you're implying that if you changed the HTML colors based on mouse events, the claim of "difficult or even completely impossible for robots" would hold?

Such a claim would be no less ludicrous.

I'd put my money on there being hundreds of people on Hacker News alone that could script a DOM-monkeying cracker for such a system. That runs with ~100% accuracy. And in under an hour of coding.

This Captcha strategy is so absolutely terrible in light of modern libraries that I'm honestly shocked you feel the need to defend it.

The best way for me to solve this dispute is to implement a CAPTCHA using some of the proposed techniques. If I fail, then I was mistaken. If I succeed, then maybe people will given G-WAN a try.
