This thread is pure cancer and i honestly feel the anger of the OP.
Make your PS4 the primary console is the only thing that comes to my mind. If he did that with another console, heres a guide on how to remove it.
"Sign into sonyentertainmentnetwork.com and do the "deactivate all" option.
Make a better, hard password and don't use that same login info anywhere else, especially gaming sites, like origin.
Also, just to say it, don't give out your info to anyone.
Also, no company will ever ask you for your login info over a message/email, no matter what they're offering."
Hope this gets solved man. Also just block the accounts that message you so he might get tired of using your account.
