When you land on a domain like 5ade026821520f50ab7dc946.wellplated.com, the first thing to ask is whether it belongs to a real person or business you can verify. This site does have an about page and legal paperwork, which is more than many throwaway domains bother with. But those positives are undercut by the fact that the domain registration itself is completely private, and the site has zero track record on the web — no archive history, no reviews, no social accounts.
For a personal blog or small project, absolute privacy is sometimes fine. But the combination of full WHOIS privacy, no contact info, and a brand-new domain means you are trusting someone who has made a deliberate effort to stay hidden. There isn't evidence that this is a scam, but there also isn't evidence that it's legitimate. Until the operator builds a visible presence or makes themselves easier to reach, the safest move is to treat this site with caution and avoid sharing personal information or money here.
