I suspect the false profiles are much higher. With people becoming more aware of internet crimes and the psychos that thrive on weak and unsuspecting people.
Any married man that doesn't want to get caught will lie about certain aspects in the profile. How do I know this? I played around with the online dating thing and then decided I didn't want another relationship. I just wanted to get laid, have some discreet female companionship, and then we both go on our merry ways.
