First of all, sorry for my english, im from latin America. Im writing this because im reading more and more threads about hacked PSN accounts, and lot of people just blame the owners saying things like no thats not possible! Liar! You gameshared and got scammed! You see, it IS possible to hack PSN accounts (xbox accounts too, netflix, spotify, twitter, facebook....any kind of accounts can be hacked) but its a lot of hard work and no one is doing that here...specially beacuse there ir an easier method to steal PSN accounts, and its not Sony´s fault. A looooot of people use same email-password combination for everything: PSN, Netflix, Facebook.......and **bleep**ty websites that can be hacked in a blink of an eye. You dont need to be a super hacker, just some basic knowledge of SQL Injection and you are surfing trough their database. In some hours you can steal from those sites millons of email/passwords combinations, those in a txt doc are called combo. Once the newbie hacker has his own, private, nice combo all he needs is a brute force checker and some proxies; the software tries to log into PSN with all of those accounts data in the combo, you would be surprised of how much accounts you can steal in a single day.
But again, its not Sony´s fault, it´s not that someone hack PSN database (like in 2011) and steals accounts directly. If you want to be safe, protect your account. Use secret question, PIN, do NOT share your information and for gods sake, if youl create an account in some **bleep**ty gaming forum or porn site: do not use same account data that u use on PSN.
