When you land on ftp.richardgraygallery.com, you see a collection of net worth articles for everyone from celebrities to Saudi royalty, all posted on the same day. That alone isn't suspicious — plenty of content aggregators exist. What is suspicious is the near total lack of transparency around who runs the site.
A legitimate content site, even a small personal blog, typically has some kind of about page or social media presence. This one has none. The domain registration is completely hidden — WHOIS returns no match at all — and there are zero snapshots of the site in the Wayback Machine, meaning it has no trackable history.
If you're wondering whether ftp.richardgraygallery.com is a scam, the main concern isn't malware or phishing (those checks came back clean). It's the anonymity. There is no way to contact anyone behind the site, no privacy policy, and no indication the domain was ever used for anything before now. Treat it as an unknown entity. You wouldn't hand your email address or any personal information to a stranger wearing a mask — apply the same logic here. Until the identity of the operator becomes clear, there is no reason to trust this site with your attention or your data.
