Finally, courtesy of @SockNastez comes some interesting PlayStation 3 online ban tips in the PSXHAX Shoutbox, as follows to quote: Here are things people don't realize:
- First off Sony's servers look at the PS3s CA Cert to see if it's on a lower firmware spoofing. If it is BAN. Most games like GTA V actually have their own CFW and mod detecting files. If you play online on DEX that is something Sony can see and ban you for.
- PSNPatch only helps it doesn't make you some modding god who can't get banned.
- About the IP ban yes, they will ban your IP so you can't access playstation.com if you get banned.
