Cornell has finally topped the rankings of elite universities across the country, including all of the Ivy League. With 273 valid accounts linked to @cornell.edu emails on the extramarital affair website Ashley Madison, Cornell blows second place Columbia and third place Stanford out of the water.
Dadaviz has some excellent charts on Ashley Madison user data, including this one about accounts using university emails: 
It is most likely the case that the accounts belong to current or recently graduated students and to current professors and administrators, all of whom are most apt to be using Cornell email, or Cmail.
The Ashley Madison hack earlier this summer and subsequent public data dump have created a media circus, one equally parts sad and hilarious. Notable family-values advocate and television personality Josh Duggar, of “19 Kids and Counting”, admitted to actively using an Ashley Madison account after being exposed. Casey Anthony prosecutor Jeff Ashton recently held a press conference to apologize for his use of the site, though he claimed that he never went through with an extramarital affair.
Ashley Madison is now offering a $500,000 award for information leading to the arrest of the hackers who leaked the site’s user database.
Go Big Red!
To be fair, doesn’t Cornell have one of the larger student populations of the schools in the graph? Would be interesting to see proportion of people associated with each school using the website, not just amount.
