How do I report a problem to Apple for an app I haven't yet downloaded from the Mac App Store?

Sometimes I want to read the privacy policy of a Mac app before downloading or buying it from the Mac App Store, alternatively contact the app's developer with a question, but the support and privacy policy buttons often lead to a website that no longer exist.

I can't find any way to notify Apple about apps with faulty Privacy Policy or Support buttons. This situation undermines user confidence in downloading apps from the App Store and raises questions about Apple’s oversight of developer compliance with these requirements. So, how do I report these apps to Apple without downloading them and going through the "Report a problem" website?

Honestly, if I find anything suspicious on the Mac App Store, why does Apple force me to download it to notify them? I detect stuff like this daily.
