You really can't prevent your accounts from being banned so be prepared to make numerous. But with the console itself its easy to prolong you consoles ban life.

First off, never be signed in when you are using any type of homebrew (Multiman, Comgenies, etc.).
Second, don't mod games that have any type of anti-ban protection.

Be smart and hide your actual console ID, visit a console ID sharing site and use one of their public Console ID's to keep your original from being banned. Its easy to swap them and will prevent your original ID from being useless.

My advice have fun with the older COD's and GTA 5! The new cod's get you banned so fast.

Just Make sure u never go on hombrew apps while online wipe your history with a Ninja v4

Make sure you use Anti Ban / EBBOTS preventing you not to get banned on he games that you may want to host on. Make sure you do homework on Jailbreak Modding before you brick your console for example which you don't want. I'm a former PS3 Jailbreak. I've been modding for 4-5 years and decided to be a PS4 gamer due to modding is boring and the PS3 is dying. Make sure you look after your CID, buy a private CID and look after it. I still have my CID from 7 months down the road.

Good luck!
