From the article:
"Cracking down on season ticket holders that it says exploit their seats on secondary ticket sites, the Chicago Cubs sent "non-renewal notice" letters to about 40 accounts today."
"After careful consideration," the letter states, "we regret to inform you we have decided not to renew the license for your account. As a result, you will not be offered the opportunity to purchase season tickets for the 2013 season."
"Those sent today's letters were identified as account holders that are more systemic in their reselling practices."
