In that regard, it is important that the due diligence obligations are adapted to the type, size and nature of the intermediary service concerned. This Regulation therefore sets out basic obligations applicable to all providers of intermediary services, as well as additional obligations for providers of hosting services and, more specifically, providers of online platforms and of very large online platforms and of very large online search engines. To the extent that providers of intermediary services fall within a number of different categories in view of the nature of their services and their size, they should comply with all the corresponding obligations of this Regulation in relation to those services. Those harmonised due diligence obligations, which should be reasonable and non-arbitrary, are needed to address the identified public policy concerns, such as safeguarding the legitimate interests of the recipients of the service, addressing illegal practices and protecting the fundamental rights enshrined in the Charter. The due diligence obligations are independent from the question of liability of providers of intermediary services which need therefore to be assessed separately.
