When you visit centropoholics.com, your browser is talking to a server that has no encryption at all. That is a fundamental safety problem. Without HTTPS, anyone on the same Wi-Fi network can see what you are reading or inject things into the page. No legitimate website today should operate without SSL.
So what is this site? It is an old fansite dedicated to the films of Roland Emmerich and Dean Devlin. The domain has been around since 2003, and the Wayback Machine shows it has existed without incident for many years. There are no blacklist flags, no malware reports, and no complaints of scams associated with this name. But all of that history does not erase the plain fact that the site is currently broken from a security standpoint.
For a personal hobby project, you might expect missing legal pages or a lack of social media. Those are not red flags here. However, the absence of HTTPS is a dealbreaker. If you are asking 'is centropoholics.com a scam?' the answer is not that it is intentionally fraudulent, but that it is dangerously insecure. Do not use this site for anything that requires privacy, and consider not visiting it at all without a VPN or a browser that warns you about unencrypted connections. There is no reason to take the risk.
