Setting request quotas per natural human. However, that has some problems to solve:

1. Who gets to decide who is a different natural human? I'm working on uniquonym (https://lemmy.amxl.com/c/project_uniquonym) that will leverage governments to decide this; other solutions include https://proofofhumanity.id/ and Worldcoin.

2. How do you avoid this becoming a supercookie tracking solution that badly impacts privacy? Zero-knowledge proofs provide some help here - there are ways to create an ID that changes on a certain frequency and is different per site, but different IDs can't be correlated, preventing long term tracking and cross-site tracking, while still providing enough to rate-limit per natural person.

3. How do you stop people selling their identity to scrapers? This is a hard one to solve, but there are protocols that make it harder without giving up sensitive information or being interactively involved on an ongoing basis.
