This address belongs to a content delivery server used by WhatsApp and Facebook. When you land on it, you're seeing an internal error page — not a scam site. Unlike a typical online store or service, this hostname isn't meant to be visited directly. There's no privacy policy or contact form because there doesn't need to be: it's infrastructure, not a business.
The security side checks out: a valid certificate, clean reputation, and no malware flags. The lack of a web history and ownership records are standard for a subdomain of this kind. In short, media.fcgk12-2.fna.whatsapp.net is exactly what the name suggests — a media server for WhatsApp. There's no transaction or personal data to worry about here. If someone claims a review of this site, they're missing the point.
