Which European directive can serve as a defence against unmoderated comments?

Regulation 19 is relevant because it relates to the liability of online platforms for user-generated content. This particular regulation offers a safe harbor for intermediaries, meaning that platforms are not held liable for the content posted by their users as long as they act expeditiously to remove illegal content once they become aware of it.

This serves as a defense against unmoderated comments by essentially providing a legal framework that protects online services, such as social media platforms or forums, from being prosecuted for the comments and discussions that take place among their users. The rationale behind this is to encourage free speech and open dialogue on online platforms while placing the responsibility of monitoring content primarily on the users themselves and allowing platforms to remove harmful or illegal content when notified.

The other regulations listed do not specifically address the issue of intermediary liability in the same way. Understanding Regulation 19 is crucial for anyone involved with online platforms, as it directly impacts how they manage comments and interactions within their environments.
