Well I'm on PSH alot and I can honestly say within the last 6 month's users have been hacking more. Also over heard 2 guides and mvp's talking that they hack as well. So is this secretly condoned. Just saying.
Get your Portable ID!
So now that most users of PS Home are hacking,will they all be banned or will Sony patch it?
As was stated not every user hacks/exploits in PlayStation Home.
I'm sure Sony will patch these issues eventually as they always do, it will just take time and as for the ones who carry out these acts, they run a very large risk of being banned as well and they have been in the past.
So the answer to your question is all of the above.
