What is with HN recently? I just do not understand why the uber-creep factor is out in force.
Even if the image set is replaceable and you dont' have to use a naked lady, that is the default demo, and the stated objective of the site is Strong Password == Naked Lady.
Aside from the blatant sexist targeting, this is trying to take advantage of entirely the wrong impulse. Associating a strong password with the human drive for porn doesn't actually encourage any better understanding of strong passwords or why they should be used.
If this were to be something like 'pwnyourpassword', and demonstrate how easy it'd be to crack your password w/ a dictionary attack, then this wouldn't be either as exploitative or crass.
Instead, the mechanism is, lets distribute pixel art of naked ladies to incentivize instead of teaching/demonstrating.
Yeah, that's the society i want to live in. :|
