> All apps listed on alternative app marketplaces are submitted to a Notarization process with Apple. Notarization is a baseline review that applies to all apps, regardless of their distribution channel, focused on platform policies for security and privacy and to maintain device integrity. Through a combination of automated checks and human review, Notarization helps ensure apps are free of known malware, viruses, or other security threats, function as promised, and don’t expose users to egregious fraud. Apple does not enforce the App Store's high standards for business practices and content on apps distributed through alternative app marketplaces.
So what I understand is that it's a baseline check for security, technical issues etc. Content moderation doesn't seem to be a part of it.
