YaK is a brand-monitoring crawler operated by Linkfluence, which Meltwater acquired in 2021. The bot collects web and social content so customers can track brand, competitor, and topical mentions.

Operator: YaK
Type: Monitoring

How Centinel checks it

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

YaK 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 in the /validate response sets access_allowed to true only for a verified source that your tenant allowlists. A policy rule can allow or block this crawler by its category, Monitoring.
