Man sues Craigslist after post said he was cheating on his GF

A New Jersey tech executive is hauling Craigslist to court because an anonymous person posted on the site claiming he was a serial cheater — and then asked readers to out the cad to his girlfriend, whose email ­address was listed in the posting.

John Goullet’s longtime girlfriend, Theresa Olguin, received an email from a reader named Adam Cooper on Dec. 30, according to court papers.

The posting read: “PLEASE TELL MY FRIEND HER BOYFRIEND IS CHEATING.”

It said, “I cannot tell her because we have people in common . . . She deserves to know while he is screwing dozens of women even younger than his own kids.”

Olguin, 49, a wardrobe stylist who has been with Goullet, 53, for three years, was not pleased.

She had also received a mysterious letter in April at her Trump Place apartment.

It read, “I know you have been with John for awhile. I feel you should know that I have seen him with another woman several times . . . It is not platonic.”

Goullet, an exec in the IT staffing firm Diversant, is suing Craigslist, demanding that the site reveal the snitch.

He says in court papers that the cheating claims are false and malicious.

He told The Post, “It’s a private matter and I don’t want any attention given to it.”

Olguin could not immediately be reached for comment. Craigslist did not return a message.
