I have no idea of the actual amount of effort that they went through, but you have to remember that Penn and Teller have a massive show in Vegas, plus television shows, books, speaking engagements, appearances on other TV shows, music videos, movies, video games in the 90's, and more. So, they're engaged with a ton of different industries, not to mention as stage performers who interact with audience members, they're frequently exposed to the public in risky ways. They almost certainly have a large and very expensive team of lawyers. What a large team of expensive lawyers would reasonably charge to chase down a defendant across multiple nation's borders over several months, I wouldn't dare to guess.
