The hackers who procured and recently published Ashley Madison's internal databases, the so-called "Impact Team," have claimed that the accounts in the databases were predominantly, in fact "90-95%" owned by men (see graphic below). Is this true or is there reason to believe it to be true?
Here's an independent verification of the leak, analyzed in further detail:
While you can remain skeptical of this source, as well, you could also download the data leak yourself and analyze the data. Similar to faking the moon landing, it would take more effort to fabricate the data (clearing up any foreign key issues, evidence of tampering, etc.) than it would to just leak the database as it was retrieved from the Ashley Madison servers.
Note that the 'as user reported' split is 84.96% Male : 15.04% female, fake and unused and unconfirmed and unpaid profiles included.
Overall, the picture is grim indeed. Out of 5.5 million female accounts, roughly zero percent had ever shown any kind of activity at all, after the day they were created.
The men’s accounts tell a story of lively engagement with the site, with over 20 million men hopefully looking at their inboxes, and over 10 million of them initiating chats. The women’s accounts show so little activity that they might as well not be there.
Sure, some of these inactive accounts were probably created by real, live women (or men pretending to be women) who were curious to see what the site was about. Some probably wanted to find their cheating husbands. Others were no doubt curious journalists like me. But they were still overwhelmingly inactive. They were not created by women wanting to hook up with married men. They were static profiles full of dead data, whose sole purpose was to make men think that millions of women were active on Ashley Madison.
