For those who solely use Netflix on their CFW PS3's and think they won't get banned...
Well it finally happened to me after 6 long years, (I know CFW's aren't that old, but my console is).
I never once played a backed up game (little lone a PSN game) online on my CFW PS3,
I just wanted the added hombrew apps like Showtime for my home media server.
I only used PSN for Netflix and immediately logged out after Netflix was allowed to proceed
and made sure of it every time.
Today I got the dreaded
"Access to the PlayStationŽNetwork by this account has been banned or temporarily suspended." message.
I'll be waiting 7 days before calling them to see if I can can be unbanned.
So for those who honestly just use it for Netflix please read STLcardsWS guide.
Sadly my modem/router doesn't have these settings available to me,
so I couldn't otherwise I wouldn't be posting about this totally awesome experience.
