I played online numerous times in my CFW PS3 and never got banned, never used some sort of protection available today and still got online access on my console.
Even my friends see's my "What's my playing" status running a Multiman ) and those my friends are legit ones but they really never bothered about me as long as I played with them fair square. Still I never bothered playing BOPS2 on my PS3 or either of its sequel nor the COD series, why? I played it on my PC and thats fair enough.
As for netflix, you cant bypass that easily since when you login to netflix, it requires you to login to PSN first then your Netflix account. If you have a SmartTV, just download the Netflix app and use that instead. Been watching netflix rentals on my Samsung SmartTV.
