Cause warez distributors have no ethics.
BTW - Not everything is bandwidth, since a lot of warez use some form of free disk space and leech off other provider's bandwidth. They just want the money.
I used to be in the warez scene, but not anymore (And been clean for quite a while). The inclusion of trojans and viruses just isn't worth it.
Remember, warez izn't free. YOu pay for it in the form of trojans and virus.
If you like having SubSeven, BackOriface, Hack a Tack, etc.. on your computer, be my guest. Its better just to shell out the money and buy a decent program. Besides, how many programs do you actually use on a regular basis anyways, not all that much.
