The Sydney woman identified only as Jo called in to the NOVA show hosted by presenters Fitzy and Wippa who were discussing the website and
The website, which uses the slogan "Life is short. Have an affair", was set up for married people seeking partners for affairs.
The DJs asked callers to ring in if they wanted to check whether their partners had an account on the website. Jo said she had suspicions as her husband acted strangely when he heard the website mentioned on the news.
"When that little thing came on the news about the Ashley Madison hack, he sort of went a bit funny," Jo said. "I asked him straight out. He said, ’Don’t be stupid. We’re married, we’ve got two kids.’
She also said that he kept his phone close by him, his hours at work had changed and he could not account for some money.
She gave the DJs her husbands details and they searched the system for him.
"We’re putting him into this website right now and his details have revealed that he’s actually on the website, Jo," said radio host Fitzy.
"Are you serious?" Jo asked. "Are you freaking kidding me?"
Fitzy replied: "Yeah, no, no."
Jo went on to call the website "disgusting" before hanging up.
You can hear in their voices that the DJS are very uncomfortable after the exchange.
"Oh, I don’t know if we should have done that. That hasn’t left me with a good feeling. What a horrible situation to be in," Wippa said.
The presenters reiterated that just because someone was linked to an account doesn’t necessarily mean they’ve cheated - or even that they were planning to.
But many listeners weren’t happy with how things played out either, taking to Twitter to voice their disapproval.
