Question: Is there a protocol that allows users to import their profiles and activity from other websites, and use that data to establish trust and loyalty?

The Reclaim Protocol is a digital identity verification system that uses zero-knowledge proof digital signatures to establish a user's identity and reputation based on their online activity. It can handle onboarding and loyalty profile imports, Know Your Customer (KYC) verification, on-chain attestations and proof of personhood validation. It's a decentralized protocol for identity verification, onboarding and loyalty, and can be used in a variety of settings like games and DeFi.

Another interesting option is Dock, which offers a system for creating trusted, reusable digital ID credentials from verified information. It offers instant verification with QR codes, ID wallet integration and automated paid verification, and data privacy is protected with zero-knowledge proofs. Dock is built on W3C open standards and can integrate with a variety of digital wallets and verification services, so it's good for industries like health care and finance.
