i played ghosts 3 dayz ago for 4 hours no ban (PS3ITA 4.50 DEX) logged off n came back on the next day n got account ban
then made new account didnt mod stats waz using a debug self, used psninja n psnpatch to delete CFW n change CID PSID n MAC.. DIDNT use a anti-ban n connected and attach b4 i logged on n diconnected target manager b4 i logged off n still NOT cid banned or from ghosts 4 3 days now

this may work 4 u or mayb im jus really lucky
EDIT: dont use anti-ban.. they look 4 ppl using that shit n gets u banned faster then not using it
