The person who owned the domain was kind enough to post his page analytics for the few months that his site was in operation:
Notice that this person had 250,353 unique visitors to his site. From here we can do some rudimentary, albeit naive, mathematics.
Now, to make the math dead simple, let's assume 250,000 visitors to the website were bona fide teenage virgin pirates. I'll discount the difference of 353 because at least 1 of them was me, 1 was Apple, 1 was their lawyers, and because App Store developers are quite aware of the piracy of their applications. Moreover some people may have accidentally stumbled upon the site when searching for pictures of monkey balls.
Let's assume, again, for simplicity, that the price bracket is $0.99.
If every hairy palmed pirate downloads 1 application then we have a lower-bound loss of:
1 (download) * 250,000 (hairy palms) * $0.99 = $247,500
Now the maximum number of applications that an iPhone can hold is 144. This gives us a theoretical upper-bound loss of:
144 (download) * 250,000 (hairy palms) * $0.99 = $35,640,000
Realistically, only the pirate with the hairiest of palms would have this many applications on their phone. So for the sake of argument let's assume the average pirate downloads 10 applications then we have:
10 (download) * 250,000 (hairy palms) * $0.99 = $2,475,000
In even the minimum case this is a significant amount of cheddar. If 25 developers evenly shared the revenue from $247,500 that would be $9900 for each developer before Apple's cut of your pie.
Whether or not $0.99 applications like WooHoo or the Chuck Norris Joke Generator deserve any of this is left for another post.
