While some illegal activities ON the network (damaging third parties) are treated differently from illegal activities AGAINST the network (damaging internet service providers themselves), the Dutch government (Ministry of Economic Affairs) is now funding an anti-botnet initiative called Abuse IX (Information Exchange) launched by KPN, SOLCON, Tele2, UPC, XS4ALL, Zeelandnet and Ziggo. Dutch domain name registrar SIDN is also providing financial and technical support and the project is endorsed by ECP as well.
As the project involves the identification of contaminated PCs, one has to assume that the ISPs are planning on doing something against that whenever they come across those infected PCs. It is not clear whether any of the remedies considered will require a court order.

Perhaps this post should have commenced by indicating that the ‘research’ has been sponsored by a group of organizations and businesses that when put together, are widely being regarded as the foundation of the Dutch ‘freetard‘ (internet) economy, oftentimes influencing various policies of the Dutch government, typically resulting in non-intervention when it comes to online piracy, which in itself is a big money maker for Dutch access providers, Dutch hosting providers and ad brokers as well. The organizations and businesses are: XS4ALL, DELTA, CAIW, KPN, Ziggo, The Royal Association of the Book Trade and the Dutch Ministry of Culture and Education.
