A file sharing program used mostly by teens and those new to the internet because they don't know that it is invading your system with spyware, adware, trojans, foistware, viruses, heck and probably the frickin devil. Can be used to download anything from child/rape/bestality/necrophile porn to music (which the riaa
have a good chance of finding). Mostly used for the former. Also known as a testement to what advertising is doing to the internet.
The bitches that made Kazaa should crucified for the crap they let their "safe" program do.
