In Prague, Czech Republic, a Brazilian Jiu-Jitsu academy recently confronted an unusual but serious problem: a visitor attempting to pass himself off as a blue belt. The deception was uncovered by none other than Fernando Araujo, a highly respected black belt from Brazil who has lived in the Czech Republic for more than 15 years and built the Jungle BJJ affiliation into one of Europe’s most recognized academies.
The incident began innocently enough when a guest arrived at Jungle BJJ and introduced himself as a blue belt. But as soon as he stepped onto the mats, his lack of technical ability raised immediate doubts. What started as quiet suspicion soon escalated into a confrontation that the entire community would be talking about.
A Photo Request That Sparked Alarm
After training, the visitor asked to take a picture with Araujo, the academy’s head instructor. While such requests are normally harmless, in this context it raised a red flag. To Araujo, it looked like the guest might use the image as “proof” of his claimed rank—an attempt to create false legitimacy.
In his official statement, Araujo did not mince words:
“A very upsetting situation has recently happened in our gym. A visiting student took a picture with the head coach in an attempt to add legitimacy to a self-promotion. Luckily, the student’s execution of techniques during practice and the request for picture afterwards caught the coach’s attention and he managed to react accordingly.
Respecting ranks is crucial for the safety of the practitioners. Our reception collects visitors’ information about their gym of origin and supervising black belt for that exact reason: safety is our priority. Oss! 🤙”
Confrontation on the Mats
In a video that spread quickly through the BJJ community, Araujo can be seen addressing the situation directly. After contacting the man’s supposed instructor, Andy Roberts, he confirmed the truth: the visitor was not a blue belt at all.
“I contacted Andy Roberts. He said, yes, you’re not a blue belt. You’re like me, you’re not a blue belt,” Araujo told him. When the visitor tried to reply, Araujo cut him short, making it crystal clear: “No, no, no, but you’re not a blue belt. You’re not a blue belt.”
The black belt’s frustration was obvious: “Man, you’re a liar. You’re like me. I’m not going to tolerate that. I don’t want to talk to you anymore.”
Araujo further explained that the deception was easy to spot: “It was clear to tell by the way you’re practicing your techniques.”

Why Belt Integrity Matters
While the incident may seem small, it underscores a larger issue in martial arts: the integrity of the belt system. Belts are not just symbolic—they communicate skill level, ensure training partners are matched safely, and protect practitioners from injury.
When someone misrepresents their rank, they undermine trust on the mats and potentially put others at risk. This is why responsible academies, like Jungle BJJ, take the precaution of collecting visitor information about their home gym and supervising black belt.
For Araujo, the message was simple: belt ranks must be earned honestly, through proper training and legitimate promotion. Anything else threatens both the culture and the safety of the sport.
Community Reaction
The Prague incident has already sparked conversation across the BJJ world. Many practitioners expressed disbelief at why someone would attempt to fake a rank, knowing that their abilities—or lack thereof—would be exposed immediately in sparring. Others applauded Araujo’s decisive handling of the matter, praising him for upholding standards that protect students and maintain the credibility of the art.
Ultimately, this episode serves as a reminder: in Brazilian Jiu-Jitsu, respect for the belt system isn’t about vanity. It’s about honesty, safety, and the integrity of the martial art itself.
