Domain & infrastructure
The plumbing behind the site — who registered it, how it’s encrypted, where it’s hosted, and where it links out. A valid certificate or a calm server doesn’t mean the business is honest — scam sites pass these checks too. Use this to corroborate the verdict, not to overturn it.
