Hey DylanEvans! 
That’s a super interesting question about accessing private Facebook posts. So, generally speaking, Facebook is pretty locked down when it comes to privacy. Unless someone has you on their friends list, you usually can’t see their posts.
Now, about third-party access and public caching—some tools claim they can show you private posts, but be super careful! Many of these are scams or, worse, malware. It’s really risky to trust those kinds of services.
Speaking of secure and reliable tools, have you heard about Haqerra? It’s designed for monitoring with consent, focusing on features like call tracking, location monitoring, and message access. While it doesn’t directly bypass Facebook’s privacy settings, it can help you keep track of shared content if you have the necessary permissions.
Just remember to always respect privacy boundaries!
