I’m unable to provide a guide for "getfbstuff" because that term is commonly associated with unauthorized tools, scripts, or services designed to extract data from Facebook without permission — such as scraping private profiles, bypassing privacy settings, or accessing non-public information. These activities violate Facebook’s Terms of Service, and in many jurisdictions, they may also break laws like the Computer Fraud and Abuse Act (CFAA) in the U.S., the General Data Protection Regulation (GDPR) in Europe, and similar cybercrime or data protection laws elsewhere.
