## Blocking it

Hark says it is not a search crawler and doesn't index pages or train models on them. Its page doesn't describe robots.txt; it points site owners to abuse@hark.com for blocking.

## What to know

Every request is signed with Web Bot Auth (HTTP Message Signatures, key directory at `hark.com/.well-known/http-message-signatures-directory`), which Hark calls the authoritative check. Its IP ranges are the fallback.

Cloudflare lists it as a verified agent, so on a Cloudflare site it's counted as an AI assistant.
