PS4 Crack account Ban?

Good day everyone, I bought a PS4 cracked account which include 1 game from a seller. The seller told me that account can be play as offline only. He asked me to create id -> type in his ID and password -> and download. After that, he asked me to login using his ID and do not active as primary whenever I want to play. I checked the ID using Playstation apps, the ID has 0 trophy, no activity and no friends. (Maybe it is a new account) The name of the account is something like bjqeybd, yea some weird name. So, is it safe to play using his ID (and not using it as primary) ? I mean can this lead to a ban? if yes, Account ban or Console ban? Thanks in advance.
