Fisnyak.ru isn't a shop or a service that asks for your credit card, so the usual e-commerce red flags don't apply. It's a Russian-language entertainment site that's been around since 2009, offering movie listings, humor, recipes, and a forum. The domain is old, the SSL is valid, and it's never appeared on any blacklist. That's a stronger track record than most hobby sites.
What you should watch out for is the login box on the homepage. The site seems to have a forum with user accounts, but there's no privacy policy visible. For a site that collects even a username and password, a clear policy on how that data is handled would be reassuring β and it's missing. That doesn't mean fisnyak.ru is a scam; small forums often skip the paperwork. But if you do sign up, use a password you don't reuse elsewhere.
The lack of contact info and an about page is normal for a personal project of this kind. The site has been quietly humming along for 16 years without incident, which is more than many newer blogs can say.
