Sony has recently revised the terms of service for the PlayStation Network. In the newly formed, and legally binding contract that you sign when accepting the TOS of the PSN, Sony has cleared itself of possible future lawsuits stemming from negligence on their part. The amended agreement comes in the wake of hackers taking down the PlayStation Network (and other Sony Online properties), and divulging personal information of their users. The privacy breach was one of the biggest of its kind, with the PlayStation Network (and other Sony properties) containing tens of millions of users’ sensitive data.
As outlined in the new TOS: “Any Dispute Resolution Proceedings, whether in arbitration or court, will be conducted only on an individual basis and not in a class or representative action or as a named or unnamed member in a class, consolidated, representative or private attorney general action,” which means, you can’t enter into a class action lawsuit against the company unless Sony agrees to it.
