When you come across a blog like korindiehacker.bloffy.blog, the first question is whether it's a genuine personal project or something less straightforward. For a tech blog that claims to have scored a perfect Lighthouse 100 after removing Next.js, the technical claim is plausible — but the context around the site itself is thin.
The domain was registered just over a month ago, and there's no about page, no social media links, and no way to identify the person behind the articles. An anonymous blog isn't inherently a scam, but it does mean you're trusting whatever you find there without any reputation to judge it against. There's no blacklist history or security warnings, which is the baseline you'd expect from a legitimate new site, but also from a throwaway domain.
If you're considering whether korindiehacker.bloffy.blog is fake or a scam, the honest answer is that there's not enough evidence either way — the site is too new and too bare. The single contact email sits on a different domain, which makes it harder to verify who runs the show. For now, treat it as an unknown. There's no obvious danger, but no reason to treat it as credible either. If you're looking for tech tutorials, you're better off sticking with established blogs that have a clear author and a history of publishing.
