If people would read the posting on the thread that I indicated that everyone should read, they would know that all it takes is an email to me and I will reactivate port/sprint for you to use at your own risk.
I'm pretty damn sure that sprint is safe ...I can't say the same is true for afterburner. Port is probably ok if you use it like once or twice a day or something for emergencies...but if you draw attention to yourself, you'll be busted.
They can't afford to ban tons of people ...so, just be smart.
