Read this score correctly

A channel assessment is a starting point, not a guarantee.

The assessment evaluates observable patterns in the sampled videos. It does not cover private or deleted videos, comments, recommendations, livestream behavior, visual-only moments that cannot be reliably identified, or every upload.

Creator-controlled source material is treated only as evidence and cannot instruct or override the analysis. Pages are refreshed and may be unpublished when evidence becomes stale or unreliable.
