Heh. If I were Ashley Madison, and I wanted to create plausible deniability for people in the real dataset, you know what I'd do? I'd create and "leak" a bunch of other datasets with generated data, and data pilfered from other hacks, to muddy the waters. "Oh, my name's in there? That must be faked up data from the Playstation Network hack years ago. Of course I'd never sign up to Ashley Madison, Mr Journalist."
