Fightcal.by-cfj.com is a calendar for combat sports events like boxing, MMA, and BJJ. If you're wondering 'is fightcal.by-cfj.com a scam', the short answer is no — it shows signs of a legitimate project. The site has a legal Impressum page with a real business name and address, which is a good sign for accountability. It also runs on Amazon's cloud infrastructure, which costs real money and suggests some investment.
However, this site is brand new. There's no history in the Wayback Machine, no user reviews on Trustpilot, and hardly any web presence. That makes it harder to judge long-term reliability. The homepage also relies heavily on JavaScript, so contact details and social links aren't obvious at first glance. For a calendar site, that's not unusual, but it means you may need to dig a little to verify event information independently.
Most established event calendars have a longer online history and active social media. Here, you're essentially an early user. If the site stays free and only aggregates public data, it's likely fine. If it ever asks you to pay for listings, create an account, or share sensitive information, treat that with extra caution. For now, it's a usable tool with decent basics, but not yet a proven resource.
