The fact is, you can claim it's not usage based, but people who have done more are being shaped more.
Easy way to decrease demand, is to STOP signing up new customers, especially if you can't support the clients you already have.
Nevermind what AH "claims", my account is shaped ALL DAY LONG NOW, and has been since Sunday 15:00.
Oddly enough, my Business Uncapped has not been able to download torrents at more than 6kB/s since the same time Sunday.... coincidence???? Seems like specific user rate limiting!

What about me getting what I paid for?????
