Yes, this is a hardware ban, to go a little bit more in depth its most likely because you were cheating, HOWEVER if it was a false ban, which did happen to me before I started cheating you can usually work something out with there support team, however if you were actually using a cheat then good luck trying to prove yourself clean.
Your best bet is to first use Selfos method seen here
Its a trusted method and has been working for a while, however if you are willing to pay a price you can just contact sync, he will take you through some of these steps and he will also offer an exe that makes some of the manual steps automatic, however keep in mind they do the same thing just in a different way. Im not completely sure where Syncs thread is at the moment but I'm sure its on the second or first page of the black market.
happy cheating.
