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. The score reflects the evidence collected on the displayed analysis date and does not update automatically.
