When to Use It
Facebook impersonation usually shows up in a handful of recognizable situations. A profile using a friend's or family member's name and photos messages you asking for money or a "favor," often claiming their old account was hacked or locked. A Marketplace seller has a profile that is only a few weeks old with almost no history, selling something priced to move fast. A page claiming to represent a real business, charity, or public figure is asking for payment, donations, or personal details through Messenger.
A Facebook scan checks account age, cloned-profile indicators, linked accounts, and photo history together, so you are not relying on a gut feeling about whether "this looks like the real Sarah" or "this page looks official." It is built to help you verify someone you are already talking to or considering buying from, not to look up or track someone who has not contacted you.
