This reminds me of the now defunct discount code thread on this forum. AA tolerated it for a while, and then when it became really popular, went after it with a vengeance, threatening litigation, and other penalties. And that thread was simply a compilation of codes that were easily ascertainable on the internet with a simple Google search. The conduct AA is going after now is, IMO, much more egregious. When AA wants to shut something down, it has proven to be quite efficient at doing so. If I was a fraudster or miles or other benefits gamer, I would be quite nervous right now.
