alexsci.com is a personal blog and hobby site, not a store or a business. The person behind it goes by Robert and uses the site to share writing about internet technology and small coding projects. So the question 'is alexsci.com a scam' comes down to what you expect from it — if you're looking for a retailer or service, you're in the wrong place. But as a personal blog, it checks out fine.
The domain has been registered since 2013, which is uncommon for scam sites. It's hosted on Google's cloud platform, uses a valid SSL certificate, and has a long, clean history in the Wayback Machine. There are no privacy or legal pages, but that's completely normal for a personal blog that doesn't collect payments or handle user logins. The only real gap is a lack of contact info on the homepage — there's an email address gated behind JavaScript and a Mastodon handle, but nothing immediately visible. Most hobby blogs do better here.
If you're wondering 'is alexsci.com fake' — probably not. It looks like exactly what it claims to be: one person's corner of the internet for writing and side projects. There's nothing here suggesting deception or risk. Just don't expect a business-grade setup, because it's not trying to be one.
