Deleting Users after Ps3 Gamesharing?

Someone on my friends list saw that I was playing minecraft and asked if we could gameshare so he could get it. I said ok and gave him my email and password. He tried to download it and told me it didn't work and he gave me his information so i could look at what he had. I never downloaded anything either but now i have a user profile that ill never use again. How do i delete it? And if I do delete it, would anything happen to his account on his ps3? I'm still fairly new to my ps3 so i don't know what i'm doing. D: thanks for your help!

I'm on xbox, but an expert at these stuff. If you 'delete' his account you are not actually deleting it, you are only removing all of his info from YOUR console. All his info is synced with sony's cloud servers, so if you 'delete' ie remove his account from your ps3, it will not affect his account

Basically what Saad said. All you're doing is removing the USER profile, NOT the actual *account*. So removing the User profile *does not* affect any PSN account data.

As for him not being able to get it working, you haven't provided exact details why he said it wouldn't work (system activation, not enough space, etc.). So without further, precise, details about why he can't get it, then there's no other help to provide.

I'm not sure how to delete a user profile but deleting one won't affect the user itself so you're fine.
