George Hotz, also known as "geohot," hacked the PlayStation Network by exploiting vulnerabilities in the PlayStation 3's security system. He used reverse engineering techniques to discover weaknesses in the console's firmware, allowing him to gain access to restricted areas of the system. This ultimately enabled him to create custom firmware and jailbreak the console, which led to unauthorized access to the PlayStation Network and the ability to run pirated games. His actions sparked significant controversy and legal battles with Sony.
Yes it is
Yes, it will be fine.
The PlayStation Network can ban your PlayStation account and stop you from using the PlayStation Network, but it is not a hack. The related question contains reason for being banned and offers a link for more detailed explanations
Basically Sony sued George Hotz, who basically is known for being the best hacker for the PS3 and the lawsuit they agreed to was that George would stop jailbreaking PS3's so if anyone is as good as Hotz, then yes but I doubt that
Playstation Plus does not have anything to do with hacking on the PS3 and is a Playstation Network premium service
Yes, that's illegal.
i have tried and failed up to 20 times i have hacked stuff from before i was 13 i know what i am doing sorry cant hack the internet from the playstation
Since it is a criminal matter no information on the hackers will be released
Not if you don't want to risk being banned from the PlayStation Network. With the new PlayStation Network security software it may not be as easy to get away with just creating a new ID if your are banned
don't do it, if you get caught playstation network will permanantly ban you from using playstation online from that address
You don't even asking about doing that can get you site ID blocked from the PSN
Yes, do it and you will get banned. The will be back to lvl 1 or or get banned for ever
