Authority: not enough signals yetClear

Why we're not scoring this yet

We withhold an authority number until independent evidence (global rank, link-graph presence) has accrued. The facts we do have about this site are shown below — we'd rather say “not enough signals yet” than invent a low score.

Safety evidence

No unexpired threat-feed result; name-similarity check available (recorded about 38 days ago); 3/3 transport and email checks available (oldest recorded about 38 days ago). This is evidence coverage, not a probability that a website is safe.

Recorded HTTPS check did not confirm a valid connection
No MX and no DMARC (mild)

Correction review promise

Official facts can help this public profile, but publication waits for moderation, evidence, and owner-proof gates.

Correction review promise: Every submitted official fact is saved for moderation before it can change the public profile.
Evidence before publication: Reviewers compare your official URL, evidence URL, and note against the visible report findings before accepting changes.
Owner proof before control: Unverified corrections can improve the report, but owner status, DNS control, and paid outcomes still require proof.
Secure same-site intake: AboutUs accepts this public correction only from AboutUs pages, keeps the response uncached, and rate-limits noisy requests.
