So, you remember that whole “Your shit got stolen by hackers because Sony wasn’t doing their job” thing a few months back? Well, you should sue (:D). Wait, did you update your PSN account? Was there a new Terms of Service and did you read it. You did and you didn’t read it?
Then you can’t sue them.
As reported by Ign.com, Sony rolled out a new Terms of service agreement on the PSN that states:
Any dispute resolution proceedings, whether in arbitration or in 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, unless both you and the Sony entity which you have a dispute specifically agree to do so in writing following initiation of the arbitration. This provision does not preclude your participation as a member in a class action filed on or before August 20, 2011.
This comes after Sony was handed a class action lawsuit a few months back because of the whole hacking problem. Pretty much, if your name isn’t on the lawsuit before the date they said, you can’t sue them and you will just have to stick with it. You can check out the link for more info.
