Source from legislation: In particular, small and micro enterprises as defined in Title I of the Annex to Commission Recommendation 2003/361/EC, should be expected to be subject to less burdensome obligations than larger service providers. Therefore, taking into account the state of the art and the availability of technologies and their costs, in specific cases it may not be proportionate to expect small and micro enterprises to apply preventive measures and that therefore in such cases these enterprises should only be expected to expeditiously remove specific unauthorised works and other subject matter upon notification by rightholders.
