When you land on nsam.dotnxdomain.net, you're greeted with a bare page that just says "It works!" — and then nothing else. That's because the site can't actually be reached: the SSL certificate is set up for a different domain, so browsers block the connection. For a personal blog or test page, that's a clear sign something is off.
Most hobby sites at least have a working URL and some indication of who runs them. Here, there's no about page, no contact email, and no record of the domain in WHOIS — it's as if the site barely exists. The hosting provider (Linode) is reputable, and there are no malware flags, but those positives don't outweigh the core problem: you can't trust a page you can't even load.
If you're wondering whether nsam.dotnxdomain.net is fake or a scam, the honest answer is that it's hard to say because there's so little to go on. The best advice is to steer clear until there's a working certificate and some basic transparency about who owns the domain.
