So Sony cant see sys calls anymore along with game history? Those were 2 main factors of getting banned on FULL CFW not the Hen crapIt's because it's easier than you think. Just don't run any homebrew online and don't cheat. CFW and webman are undetectable.
What you do offline they don't know. So what I do is just change one value in the dns setting back and forth to have internet or not while always connected be on my local network.
