Do you really think a bunch of scrapers' time is more valuable then yours? I'm assuming that you have the ability to create this great piece of content that people want to have so I think your time would be better spent either creating more of said content or pursuing other endeavors other then making some kids waste an additional 15 minutes figuring out a way to solve an interesting puzzle.

If they can easily find another source to scrape the same data, said data probably isn't worth spending this much time and effort protecting anyways.
