Authority 50/100— ahead of 50% of the August 2026 scored sampleClear
Why this authority score
50 is a percentile: higher than 50% of sites we score.
How it's calculated
Prominence (Tranco rank #382,254)+5
Verified continuity: 23.3 years (RDAP registration)+10
Security & email hygiene+3
Calibration adjustment (published map)+9
Model score: 27/99 — what these reason lines add up to.
Published Authority (percentile): 50/100 — this site's rank against the August 2026 scored sample. Public Authority is capped at 99.
Safety evidence
No unexpired threat-feed result; name-similarity check available (recorded about 29 days ago); 3/3 transport and email checks available (oldest recorded about 29 days ago). This is evidence coverage, not a probability that a website is safe.
No caution flags in the available scoring observations; this is not a complete safety assessment
