Well, the whole point of setting up a seperate network is to avoid having to go anywhere near PSN. If you're not using it, you don't get banned! Besides, you can be console/profile/IP banned from PSN and it won't make a blind bit of difference if you're using something seperate, like Xlink Kai.
Besides, Xlink has been going for a good while and they aren't stepping on anybody's toes, I'd imagine Sony and MS are happy people can bugger off somewhere else! I do think PSN is ruined with the amount of cheating going on, which honest customers shouldn't have to put up with (nobody should, unless it's a private server). For example, I wanna update one of my many machines to 3.56 and stay legit, but I'm not rushing into it because you can have 3.56 with the patch sitting on your HDD working away, still ruining games. The new MW2 patch might put dampner on this, at least for a short while and Treyarch seem to be on top of it too.
