Anonymous, the group of hackers who are currently targeting sites like playstation.com with DDOSing attacks, has just posted the demands that must be met before they will stop attacking Sony-held sites.
The demands are as follows:
1. Sony must allow for end-user modification of the PS3, as was available prior to the 3.21 firmware update.
2. Sony must end any attempts to bring legal action to alter a product they own.
3. Sony must not pursue legal action against any collected IP address.
Sony won't agree them and people will just hate hackers/anonymous more, because they blocked PSN access.
So they failed by attacking PSN, because now even more people started to hate them.
