This is neat. Definitely checkout [1] if you're confused as to how it might be used. There are some good examples there.
These guys seem to have a unique perspective on human-data interaction and sharing. For example, the "Global Quick Add Feature" [2] is very intuitive. It seems like this is something Facebook is very interested in as it's essential to their product. I definitely agree with some of the other comments made here - I wouldn't be surprised if Facebook wants these guys working for them at least as much as they are interested in their actual product given their perspective and understanding.
The script makes 175760 permutations. For me the script takes around around 1.5 seconds to query the page each time. 175760 * 1.5 / 60 = 4394 minutes / 60 = 73.23 hours of constantly hitting the site. I'm not sure how the parallel connections it uses will impact the speed, but 3 days seems feasible. Not to say that this should ever be tried.
Yeah, it looks like it goes through each possible permutation of coupon codes for the BinaryAge Total Finder online store [1]. These codes seem to be in the format THANKSXXXX, where X is a random number/letter.
It generates a set of possible codes and then queries the website for each one of those codes. When it finds a correct coupon code permutation it outputs the code to the screen and writes it to a file. (Presumably so that the coupon can be reedemed for a free, illicit, copy of the program)
