Any recent hacked accounts from Southperry users?

The only time a lawyer will work without payment upfront in the U.S. is when it's related to physical injury or malpractice and they're almost guaranteed a nice cut at the end.
For a consumer law affair like this it'd be pay up front unless it looked likely to go class action for a nice pay out, and even then they'd require filing fees, travel, and any other up front costs.

To be honest, you're the only person I would trust to represent both yourself and us in a case against Nexon. You're the least likely to have shared any personal information and the most formal in terms of speech. Least likely to get burned for saying the wrong thing. I mean, if anyone were to take Nexon to court for themselves, they would be representing everyone. A loss would be a big one.
