It's dumb to get one-sided in any way on this. Piracy isn't cool. Mass suing people isn't really cool either.
1. Piracy is inherently wrong, it's theft.
2. Suing people outside of their home jurisdiction isn't right, especially if they have no real contacts there. You aren't giving them a fair chance to defend themselves.
Solution:
3. Sue less people, in their home jurisdiction, with local lawyers. Then jurisdiction issues and issues like these go out the window. Some people in adult are already doing it and establishing a network of attorneys to handle the cases all around the country (

If you end up on the wrong side of that suit, it's actually way more scarier for the end user. If you could choose to be a defendant, would you rather be one defendant of 5000 defendants, or one defendant of 30 defendants, in a specialty lawsuit just for you and a few others. You get way more attn when there's less defendants, and your price of settlement probably shoots up. You bet your ass these lawyers will go thru the process, win the judgements, and start seizing assets. And you bet they are going to look at who you are, and dedicate a whole lot more attention just to you.
While TorrentFreak will look at it and boast, what they don't realize is because piracy is inherently wrong, the solutions will be come more solid and concrete on how to properly do it, and to those who support piracy, that's a bad thing long-term for piracy users.
