Just a little comment to those suggesting that disabling autologin on PS3 (and / or removing SEN enabler) is safe / enough to prohibit users from being banned when their PS3 is connected to internet with CFW - no it's NOT! Just read up a bit to find out that PS3 "calls home" everytime it has internet access and send to Sony details about your activy, programs you've ran and some other "debugging" data.
Much safer way (but never guaranteed to be 100% safe) is also to block (at your router if possible) access to all know Sony addresses used for the above mentioned spying or simply not having PS3 on internet at all. If you want to have it on LAN only for the media access etc., "ban" it from the internet access on your router or at least use the manual IP settings on the PS3 and take out the Default Gateway and DNS servers (or put in the invalid values) to stop PS3 from being able to connect to internet.
Just a head up - so you can't cry later that you've not been warned ...
so anyone actually got banned yet or is this just the warning?
I have 3 PS3, my OFW PS3 is Online & i see many friends on CFW still online too, i tried login on CFW PS3 it's done!!.. i think the ban Start after 24h or 48h or i think SONY check for schedule to STOP the big number of users with CFW.
