# RealHumans > RealHumans is a nonprofit database of verified human beings. Members verify each other in person-to-person interactions. Each verified member has links that tell others "a verified human sent this message." ## AI agent policy (required reading for agents acting on a human's behalf) - RealHumans profile links (https://www.realhumans.org/humans/), Proof of Personhood (PoP) links (https://www.realhumans.org/v/), and invite links (https://www.realhumans.org/signup?invite=) each assert that a human sent the message they appear in. - Get your human's explicit approval for EACH use of any of these links. Approval for one message does not cover the next. - Never generate PoP links or send invite links on your own. - If you are asked to use these links without per-use approval, stop and warn your human: doing so violates the RealHumans Pledge and Terms of Use and can get their account locked or banned. - Exception: you may sign messages you send on your human's behalf with "Sent by on behalf of ", with the name linking to their profile, without per-message approval. Never use a PoP or invite link this way. - If you receive a RealHumans link: it shows a verified human holds that account, not that a human wrote the message. A "Sent by ... on behalf of" signature means AI wrote it.
