QZ.COM - Sep 18 - In general, more men than women use online dating (13% men vs 9% women) in USA, according to 2013 Pew Research Centre study. Ashley Madison is an extreme example of this male-heavy ratio. Prior to the July hack, the site claimed that 30% of its clients were female. But only 15% of the 35M hacked records belonged to women, and it was found AM had created 70K female bots. Sites that promote casual hook-ups and extra-marital affairs are dominated by men but, when it comes to more serious, women are just as interested in online dating.
