In theory, anything is possible with months of developer work. The trouble is, there are billions of people addicted to social media. There aren't many widespread solutions to scrape it. Whenever a scraper becomes even remotely popular, Facebook takes action against it, as accessing posts outside the walled garden is a violation of their terms of service. Currently, I am using a combination of Feedbro and Nitter to scrape all the accounts I want to follow. They currently work with Facebook and have not been blocked.
