Online dating and peer to peer marketplaces have become part of everyday life. Whether you are meeting a potential partner on Tinder or buying a laptop from Facebook Marketplace, trust is built fast and often with very little information. That speed is exactly what scammers rely on. Learning how to verify a dating profile or run a basic background check on an online match is no longer paranoia. It is digital self defense.
This guide takes a lifestyle focused and ethical OSINT approach. OSINT means open source intelligence, using publicly available information to check consistency and credibility. You are not hacking, spying, or crossing legal lines. You are simply checking what is already public to protect yourself from scams, fake identities, and emotional or financial harm.
