How face search actually works, what it can and cannot tell you, and how to stay on the right side of the line while using it.

One photo, no name, and the order that works: read the frame, search the file, then search the face.

Instagram's own search only works if you already know the handle. Six routes for when you don't.

TikTok is built to push content, not to let you search it. Six routes that get around that.

Graph Search is gone, but a photo, a mutual friend and one anchor still get you there.

One looks for copies of the file, the other for the face. Picking wrong wastes hours.

The tells in the order they actually appear, plus the two checks that settle it in five minutes.
