As a result of Virgin Media's new traffic management system, i'm about to have my bandwidth throttled for five hours each day. I'm not terribly impressed.
There's no such thing as unlimited downloads. FACT.
They don't cut you off though, they limit your service.
I agree it throws the whole industry into disrepute, but i also think pretty much everyone has got the idea by now that if you spank your connection, your ISP will...ummm...spank you back.
If you're not already aware of this as a broadband user then you need to take your head out of the sand.
