sofworld.org has an AboutUs profile for public website intelligence, ownership context, trust signals, monitoring, and owner verification.
Add the HSTS, Content-Security-Policy, and X-Frame-Options response headers.
AboutUs has not vetted this site. Everything below is what we could measure automatically. Anything you do on the site — paying, sharing personal details, downloading — is between you and the site, not AboutUs.
Current facts
Latest available measurements; dated entries retain their dates. These are measurements, not an endorsement of the site.
latest result
Domain registered May 10, 2000 — 26 years old.
latest result
Registrar on record: GoDaddy.com, LLC — unchanged since AboutUs began tracking (Sep 1, 2026).
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 77 days ago); 3/3 transport and email checks available (oldest recorded about 77 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
