Certification
Certificate not verified
zewbie does not link to IGI's report check, because zewbie has never been able to resolve it from its own network. Ask the seller for the report, and check it with IGI directly.
IGI's site refuses this network: HTTP 403 to a plain request and HTTP 202 -- a firewall challenge, not the page -- to a browser user-agent, measured 2026-09-14 and independently on 2026-09-13 from three different egress doors (see policy.unverified_sources.igi_4c_lab_grown). zewbie does not publish a link it has never resolved, so an IGI listing says so in words instead.
