FingerClone shows you a gesture — a squiggle drawn on your screen — and asks you to clone it. A human hand wobbles, overshoots, and corrects; a script flies straight. That difference is the whole product: your trace is scored, and a passing score proves a person was here.
One person, one hand, one trace. Don't automate the game, replay recorded traces, or probe the endpoints looking for the scoring edge. Three failed sessions in a row from one address and the site declares that address not human — the flag is sticky.
Scores are statistical judgments, not identity documents. A "human" verdict proves a plausible hand drew the trace — it is not a background check, not KYC, and not a promise about anything else.
