Up here (Alaska) we have about 100,000 cable subscribers along with mixed Fiber/DSL/POTS access and nearly 50,000 cellular customers with high speed data around our Metro network. I am an RF Engineer, however the network I run is IP based (satellite) and I run in the neighborhood of 250mbps forward and 30mbps return to most of the State of Alaska. I find that anywhere from 40-65% of our total traffic is "questionable", which is why I was asking about an ISP who liked their users downloading torrents. It is very difficult to gauge a users behavior if they are on an "all out" downloading binge over a weekend. Normally, a user logs in and does what they need to in a relatively short amount of time (hours). In the case of most providers, we oversubscribe our resources and have found this model is beginning to not apply to 
user behavior changes. Long gone are the days of the user turning off their computers, and our customer base (rural Alaska) have few things to do besides use the internet. This has made a "perfect storm" of sorts, as we are now seeing most of our users utilizing 70%+ of their allocated (purchased) bandwidth 24 hours a day. The vast majority of the night use is gaming, and bit torrent. It makes things much more complicated when trying to give an experience to people..

This could be the background for a statement like "a proper ISP doesn't encourage any type of traffic." We have a couple of OC-192 running to Seattle, so certain "types" of traffic can make a good day turn very badly without some traffic "management".

What is keeping your company from buying more bandwidth? I find the
excuse of over subscription to be a fail. If that's your companies
business model then it should not be whining when people are using what
you sell them. Provision bandwidth accordingly and stop being cheap and
squeezing every last dime from the end user for bandwidth that can be
had for less than the price of a burger in some places.
