The suspicious wife told the radio hosts how her husband had been "snippy", changed his work hours recently, and kept his phone close to him.
"I feel like we're on Jerry Springer," said Fitzy.
The hosts put the man's details into the site and told the Blacktown woman that he featured on the site.
After a few seconds of awkward silence, Jo said, "Are you serious?" News.com.au reported.
"Yeah I'm sorry," said Fitzy.
"Are you freaking kidding me? These websites are disgusting..." said a distressed Jo, before hanging up.
News.com.au says it was immediately clear that the radio hosts regretted the on air incident.
"I don't know if we should have done that," said Wippa.
"That hasn't left me with a good feeling. What a horrible situation to be in."
Wippa then urged Jo not to jump to conclusions.
