if everyone follows the same exact process then these things would prob last more then a few seconds....and if your modding GHOST use ImSooCools tool...ANTI-BAN works...been using it for awhile now.
My process from preventing ban....which seems to work no problem
1. I use SEN Enabler to spoof CID/PSID, delete all history and disable CFW (Control Console API for PC also works well when spoofing CID, PSNinja works as well by just using the 1st two options and PSN Patch works as well to disable CFW)
2. Then i hit up ghosts and go online while still having a working CID, once i am in i then spoof my CID to a random one
3. When i'm at the main screen online after it fetches my profile i then open up ImSooCools most up to date tool and connect and attach and then you use the ANTI-BAN box 1st before checking anything else. Wait a 1 min or so then check whatever you want.
then bam you should be good to go....i was on it for hours lastnight while doing this process.
as for GTA...i have never ben banned from there and i've been modding craziness out of that. So i don't know what everyone is doing wrong. I've used modded files and RTM tools and i have no issues.
