No, they dont ban UDID. They dont ban MS account. All they do is ban Xbox account aka Gamertag. End of story
Just going to say I'm pretty sure it's UDID or some other identifier because my main account got banned, and then like others any secondary one I created on my computer was able to connect online but not access leaderboards/paints/tunes at all. I've tried to play it on my xbox without the main account having ever booted it up on the XBOX but looks like the secondary account was already flagged. Might be able to create another account on the XBOX and only play it there but not really worth it in my opinion.
Did end up being able to get a refund for my Ultimate Edition purchase however, but just a thing to keep in mind if you want to play online in any fashion and get the tunes/paint jobs to not use the trainer online/at all or you'll risk an entire computer ban.
Does anyone have problem with the Controller? The cheats don't work for me with Controller.
You cannot use the controller for the game and the trainer options simultaneously. When in the trainer's Settings tab you see and can set the controller trigger to switch to enable/disable trainer options and switch back to controller for game use.
