I'm not sure. I think what happens a lot is they sell packages as unlimited but are actually measuring everyone, and for the few outliers going over a limit, they send an email saying you are now on a limited amount. It reminds me of a few years ago, I got a call from Comcast saying I was in the top 1% of bandwidth users and they asked if I had an unsecured wireless network because people around me were probably tapping into my router. I was going crazy with downloads, but these days with HD Netflix etc. I'm sure tons of people are using that much bandwidth.
