In order to create legal certainty, and not to discourage activities that aim to detect, identify and act against illegal content that providers of all categories of intermediary services undertake on a voluntary basis, it should be clarified that the mere fact that providers undertake such activities does not render unavailable the exemptions from liability set out in this Regulation, provided those activities are carried out in good faith and in a diligent manner. The condition of acting in good faith and in a diligent manner should include acting in an objective, non-discriminatory and proportionate manner, with due regard to the rights and legitimate interests of all parties involved, and providing the necessary safeguards against unjustified removal of legal content, in accordance with the objective and requirements of this Regulation. To that aim, the providers concerned should, for example, take reasonable measures to ensure that, where automated tools are used to conduct such activities, the relevant technology is sufficiently reliable to limit to the maximum extent possible the rate of errors. In addition, it is appropriate to clarify that the mere fact that the providers take measures, in good faith, to comply with the requirements of Union law, including those set out in this Regulation as regards the implementation of their terms and conditions, should not render unavailable the exemptions from liability set out in this Regulation. Therefore, any such activities and measures that a provider may have taken should not be taken into account when determining whether the provider can rely on an exemption from liability, in particular as regards whether the provider provides its service neutrally and can therefore fall within the scope of the relevant provision, without this rule however implying that the provider can necessarily rely thereon. Voluntary actions should not be used to circumvent the obligations of providers of intermediary services under this Regulation.
