Now, a much wiser Schulman is helping others catch the "catfish" in his new hit series on MTV inspired by the real-life documentary, "Catfish: The TV Show."
In one episode, Schulman meets Sunny, who says she has been dating a medical student online named "Jameson" for eight months.
"He's going to be an anesthesiologist. He does online classes," Sunny says of "Jameson" in the episode.
Schulman convinces Sunny to take a road trip to meet "Jameson" face to face and and Sunny later finds out "Jameson" was really a woman who was pretending to be a man online for at least four years.
"I mean who does that?" Sunny said in the episode.
As more become connected through various social media outlets, Schulman says these "catfish" hoaxes will continue.
"So long as we're not looking people in the eye face-to-face, there's always going be room, a lot of room for deception," he said.
