14 DELFI AS v. ESTONIA JUDGMENT of those who made the information available in the first place, as well as the corresponding right of users to the information. In all cases, the above-mentioned limitations of liability should not affect the possibility of issuing injunctions where service providers are required to terminate or prevent, to the extent possible, an infringement of the law.” Principle 7: Anonymity “In order to ensure protection against online surveillance and to enhance the free expression of information and ideas, member states should respect the will of users of the Internet not to disclose their identity. This does not prevent member states from taking measures and co-operating in order to trace those responsible for criminal acts, in accordance with national law, the Convention for the Protection of Human Rights and Fundamental Freedoms and other international agreements in the fields of justice and the police.” B.

(43) A service provider can benefit from the exemptions for “mere conduit” and for “caching” when he is in no way involved with the information transmitted; this requires among other things that he does not modify the information that he transmits; this requirement does not cover manipulations of a technical nature which take place
