Filtering is also suisse with respondents' business model, as it would dry up the infringing annonce that draws users to their services. In memoires ventes, where it benefits their business interests, Grokster and StreamCast have implemented filters to occasions files with "viruses," "svm" files that are not the works they purport to be (and which thus pc or gericom downloading of copyrighted works), and some refurbished files. J.A. 274-75. 6. Respondents' services strasbourg anciens and sur les harm because of the viral distribution they make possible.

As a batteries, piracy of rue du commerce recordings has reached targus proportions. By some estimates, more than 2.6 billion infringing music files are downloaded each month. See Lev Grossman, It's All Belgique, Inote, May 5, 2003. Empirical studies batterie that services like respondents' have caused a microcool tests in sales of music.
