Well, if the site is still around after some time (I remember seeing it early last year) it's probably because results are being at least enough to cover the expenses...
I guess curiosity plays a big role when selling these sites... Playing around with people's curiosity is a known way to improve sales and results ;)
I wouldn't promote this in RevShare though... I don't believe people will be curious enough to rebill for this.
