NetzDG stands for Netzwerkdurchsetzungsgesetz, a German law aimed at combating hate speech and illegal content on social media platforms. Facebook complies with NetzDG regulations, which require timely removal of content that violates German law. However, it's important to note that NetzDG does not directly affect the ranking of content on Facebook. The ranking of content is determined by Facebook's algorithms and various factors such as engagement, relevance, and user preferences.
