Looking for psn accounts

Hi guy's i just wanted to ask how do people get free psn accounts and then they sell them how do they actually get people's accounts and then sell them onto people?? Does anyone know how??

Yeah , it's easier than you think
i'm in that business right now
no so much profitable but it gets you 1k per month
why you ask this question you want to get into this business?

Is it the same as jailbreaking the ps4?
