This is a funny joke, but I can't imagine it is terribly effective.

  I did some experimentation with this sort of technique a few years ago. At first I was amazed at how naive bots actually are, but it makes sense: they're not going to spend the extra effort dealing with edge cases like this when they can just widen their net by hitting more sites. I don't know if things have changed but a few years ago this would have caught most bots.

    Yeah, but the same argument was true of captchas. Once they caught on, it wasn't long before bots adapted.
