At least there's an option. Sure there's a problem but at least there's some level of ability to rectify. PDfs of my work show up on pirate sites who make money from ads all the time and I have little to no ability whatsoever to correct that. That's just doing business in the current economy. You either have to ignore it or actively deal with it. Neither option will totally eliminate it.
