Yeah, this is a cute idea, but unless someone has actually stolen your identity because of the breach, you’re not going to win, and will probably lose court fees in the process. Here’s some advice from a lawyer on Reddit:
Equifax was very, very negligent in letting their systems get breached. But until there’s an actual injury, you can’t win any lawsuit unless there are statutory damages, which almost certainly brings it into the federal court realm. You can’t just pick a random-ass number and say “I was harmed for this amount.” No, you can’t get it for emotional damages. No, you can’t get it for pain and suffering. Unless your ID was actually stolen and used to open a line of credit, your best option is to remain in the class action.
Sounds about right.
