Ashley Madison is a website specifically for married men to seek out women with which to have affairs. It was subject to a large scale hacking during 2015 that left all of it's user's personal details avaliable on the web. A group of four (Mason Terrill, Jamie Bitmead, Perry Harding and James Etherington) decided to catalogue this data in response to a university brief.
The result of this was a series of A0 posters featuring the data from the hack. Were the complete data printed on these posters in 2pt type they would full over 1000 A0's. The group decided to omit names from the information, simply because this wasn't an exercise in exposure, more an exploration of the scale of stolen information.
