The first is impersonating an individual, group or organisation in order to deceive. The second is the use of fake personas, which the policy defines to include stock, stolen or AI generated profile photos, copied biographies, and misleading profile information used to deceive others.

Why Reverse Image Search Misses Most Impersonators A face search and a reverse image search look similar from the outside, but they solve different problems. Upload a photo to Google Images and the engine searches for that specific image: same composition, same crop, ideally the
