The problem with this type of method: once a method gets popular (because
it temporarily works), bot writers are more than likely to simply update their
bots (which should be fairly trivial in this case).

But then be careful that users of assistive technology don't stumble onto the
trap by mistake.

Cute...particularly like the fallback mechanism. Again, though: once this
catches on, bot writers will simply change their algorhythms.
