## How Centinel checks it

- **User agent**: The request calls itself this crawler. Anyone can send the same string.

AddThis.com publishes nothing Centinel can check a source against, so a match reports the name and leaves the source unconfirmed. The match tokens, verification domains, and address feeds are not published here.

## Allowing or blocking it

The [crawler object](https://docs.centinelanalytica.com/api/crawlers.md) in the `/validate` response sets `access_allowed` to `true` only for a verified source that your tenant allowlists. A [policy rule](https://docs.centinelanalytica.com/admin/policy.md) can allow or block this crawler by its category, `Preview`.
