There may be a large number of women on the internet and a large number of women having affairs but is that because they actively sought them out, or because life happened?
With all we know about gender roles and social history, outdated as it may be, how many women do you imagine are looking for a guy who's on a website devoted to cheating? Just imagine, if you will, all the women sitting around pining for the married guy who's actively into infidelity so they can hookup and later make a Pintrest page of their exploits... Seriously, in what world do you imagine that a woman would find these guys remotely attractive? Of those 12000 real accounts most of them were probably for the purpose of pre screening real life dates... one more douchebag check on who NOT to date.
