There are ISPs that do this to customers who sign up for low price unlimited bandwidth deals and then hammer them for torrents. Traffic shaping them down to 1Mbit/sec or lower means they're likely to move onto another ISP within a few months.

Legally dubious, but no other way of managing the 1% of users who are using 95% of the bandwidth in a way you'd not provisioned for (because then your economic model is broken).

Non peak bandwidth should be effectively free for ISP’s. Limiting their bandwidth during those peaks should be sufficient without losing a customer.
