Nest

A friend's phone screen lit up with alarming notifications: "Help, they're trying to delete my account!" His older friend, a self-assured internet hero, simply chuckled, "Give me a pass, I'll figure it out," unaware of the trap he was walking into.
He froze after clicking the link. The profile was eerie: the owner's face was clearly visible in the avatar, but the thick black filters transformed it into a sinister silhouette, and the username was filled with aggressive Arabic script. An icy darkness emanated from the page. He paused for a moment, but youthful maximalism overcame common sense. Leaning back in his chair, he confidently tapped the keyboard:
"Listen, you want to knock down my brother? Let's have a chat if you're not too scared."
Minutes passed. Two, three... By the end of the fourth minute, the guy was grinning triumphantly, about to text his friend that the cyberbully had simply disappeared. But at that very moment, a notification lit up the screen. The reply was icy and curt:
"Kitty problems?"
The self-assured joker barely had time to blink before he saw the chat begin to fill with terrifying text blocks. The bot didn't engage in idle arguments or threats—it simply dumped his real home address, school number, parents' names, and exact geolocation into the conversation.
All the brazenness and arrogance vanished from the boy in a split second. His finger hovered over the screen, completely frozen, and cold sweat broke out on his forehead. The former "joking boy," who had simply wanted to troll the terrifying account, instantly realized that he was completely exposed, and no one would ever want to joke with someone who knew absolutely everything about him again.

Official: the bane of all internet heroes and the bane of every chat room. His profile picture is all darkness and black filters, and his username is a terrifying Arabic script. He likes to pretend to be a friendly, silent type until the next "joking boy" decides to show off. 26 years old.
