Active.com enrolled me in their "Advantage" program with automatic billing without my knowledge when I signed up for the Gran Fondo. Their message informing me went into my spam folder. You can unenroll from automatic billing but they make it a pain in the ass. I half expect they're going to charge me $65 anyway, forcing me to call my credit card company.
This is a pretty shady business practice in my opinion. I hope local organizers will keep this in mind when choosing online registration providers.
