I hear you entirely and have done the same for a few clients of mine in the past who wanted "LOTS" of traffic overnight for certain reasons
The traffic in my experience got maybe 1:2000 or perhaps even worse where that person would go beyond the second page. So as long as you know, porn people want porn and not an automobile or a kitchette you will get your hits
On the outside it will look great, lots of impressions wasted, however, with paid advertisers they will soon realise you site converts like shite and never use you again..
Hope that helps.
