Now that's an expensive date.

An OkCupid user who was duped out of $70,000 by a man he met on the popular dating platform has filed a lawsuit against the site for failing to effectively screen members and communicate the risks associated with online matchmaking.

Michael Picciano, 65, of Queens, N.Y. signed up for OkCupid in December 2012 and was first contacted by a man named Bruce Thompson, who went by "genuineguy62," on Feb. 11, 2013, according to the lawsuit. Their relationship progressed quickly — the two began to communicate regularly, first on the site and, less than two weeks later, over personal email and text messaging. They spoke on the phone for the first time less than three weeks after that.

Over a period of about two and a half weeks that began on Mar. 29, Picciano wired a total of $70,420 to Thompson to to help cover what he said were unexpected expenses associated with his new computer parts business.

OkCupid markets itself as "the best free dating website" and it was because of this that Picciano says he trusted it to be safe and Thompson to be true to his word. This is despite the fact that OkCupid's safety tips page specifically warns users not to wire money to anyone they meet online.

The first two payments were made to accounts in the names Dennis E. Racer of Addison, Texas, and Edmond Thebeau of Ontario, Canada. The third was to MacBenson and Associates of the United Kingdom. All of the transfers were completed at Picciano's Capital One bank branch in Queens.

A couple of days after the final transaction, a friend of Picciano's found Thompson's picture and information on malescammers.com. Picciano contacted the police, who told him not to break contact, and handed over a forged check for $100,000 and a promissory note Thompson had sent him in an effort to earn his trust. Experts were unable to find any fingerprints on this evidence, nor could they trace the the check to a specific location.

The pair ceased emailing on June 6, but Picciano believes Thompson was still on OkCupid under a different user — "bigheartedbt" — as of last month.

Picciano is also suing IAC, OkCupid's parent company, and Capital One, the bank at which he made the financial transactions, for not catching the fraudulent transactions.

None of the companies named replied to Mashable's request for comment as of press time.
