First off, the limitations actually will hurt brokers, not help them. 2 games with 2 tickets per game limitation per account will kill brokers.

Second, you most certainly will need more than a password, you will need to log on with your account number or Ticketmaster couldn't enforce the limit.

Finally, I don't know what your experience is but if you think snail mail is more secure than a truly secured website like Ticketmaster you are nuts. Anybody can snag your mail and get your banking and credit card info. That is, unless you get all statements via e-mail, which belies your take. Of course, mailing in a payment allows the thief to get ahold of your info as well.
