No idea. I would assume they are.
People on the EA ultimate team forums were coming with a pretty good idea that the chat support agents were hackers, or at least some of them. They get paid minimum wage iirc, and considering you can make pretty easy money selling your coins or players, I could see it happening.
Am I the only one upset with the inclusion in divisions? H2H seasons was sweaty to me after division 6, and tournaments in UT have always been just full of Brazil teams. I might be playing career more than UT.
