hintjens.wdfiles.com is a subdomain that works as a file host for a personal site on Wikidot. If you're wondering whether it's safe, the short answer is that it doesn't show any signs of being a scam. There are no malware listings, no blacklist appearances, and the underlying encryption is current. The main thing to know is that it immediately forwards you to hintjens.wikidot.com, which is the actual page you're looking for. That redirect is intentional, not a trick.
For a personal blog, the lack of contact information, privacy policy, or detailed branding is perfectly normal. You wouldn't expect a one-person tech blog to have legal disclaimers. The SSL certificate is valid but will expire in a week, so if the owner doesn't renew it, visitors could get a security warning. That's the biggest practical concern.
When checking if hintjens.wdfiles.com is a scam, focus on whether the redirect makes sense for what you're after. It's a clean redirect with no ads or malware. The site has no history in the Wayback Machine, which suggests it's either new or not widely archived. But given that it points to an established Wikidot domain for a known author, there's little reason to worry. Just make sure to renew your bookmark on the destination site if you plan to return.
