This may be a function of both online purchasing differences by gender and the type of fraudulent schemes by which the individuals were victimized.' But obviously it is not only the porn which lets the men grab their credit cards, they are also more likely to fall for questionable investment offers. See the complete study (PDF) for a detailed analysis. Keep in mind, however, that only the known internet frauds are listed. It cannot be said for sure how many people are simply to ashamed of their own stupidity to report their damage to the authorities."
