NCAAbbs

I tried registering with my home email address but it said that it was banned. So I had to sign up with my work email address. That worked. I went to change my email address from my work to my home and still nothing. I even used a very old email address and still said it was banned. What's going on?

From the Registration page:

NCAABBS DOES NOT ALLOW REGISTRATION FROM FREE EMAILS SUCH AS YAHOO, GMAIL, OR HOTMAIL.
