The Hurricanes' jacked-up e-mail system.

Could someone please explain to me how I got on a the Carolina Hurricanes e-mail list? I went to ONE game down there, and it was an awesome game (though it would have been better if the Sabres had won), but it was an ECF game (game 5, 2006). So why is it that almost 2 years later I randomly get 2 e-mails in a week's time about how the 'Canes are doing?
