Sin Chew Daily reported that a 38-year-old man was blackmailed for S$500 to ensure that a photograph of himself masturbating in a cyber sex session was not published online.
The married man, who befriended a woman from the social network Tagged last year, said he had conducted a cyber sex session with the woman.
She took a photograph of him without his knowledge.
The woman later demanded money from him and later disappeared from the network.
The daily also said many men had fallen victim to the scam and most of the women were from overseas.
