The honest use: is this account a real person?
Crypto pitches, investment DMs, romance approaches and job offers on X very often come from accounts wearing someone else's face. Run the avatar. If it traces back to a model's portfolio, a stock library or an unrelated person's Instagram, you have your answer before you reply. This is fraud prevention and it is the reason this page exists.
Where we draw the line
Pseudonymity is not a crime. Plenty of people post under a handle for perfectly good reasons — their job, their safety, their family. Using a face search to attach a real name to someone who is not doing anything to you is harassment, it violates our terms, and it is the fastest way to get an account terminated here. If the account isn't targeting you, leave it alone.
AI avatars are changing the picture
A growing share of fake accounts now use generated faces rather than stolen ones. Those return nothing, because the face genuinely doesn't exist anywhere else. An empty result on a suspicious account is not a clean bill of health — read it as 'this face has no history', which for a supposedly real person is itself a red flag.
