Gee, removing other os sure had the desired effect huh?

Since the removal of other os, PSN security is worse than ever. The hacking and pirating was never a result of other OS it was and is a result of PSN's lackluster server security. Do you guys really think that someone with the capability to hack using other os wouldn't be able to jailbreak their ps3 and do exactly what they were doing before? Now it's just harder to control.
Anyone that has used the psn marketplace or used their credit card on PSN at all, I suggest you call your credit card company and either cancel that card or have them watch for unusual activity.
