It seems probable that they just looked at the BusinessWeek forums on which the exploit was posted, and denied the applicants who they saw discussing it.

If thats the case, its very unreliable. Denying admission based on a post on a forum...gotta love the digital age.

In an age when many employers seem happy to deny employment based on social networking profile posts and pictures, I suggest that it might teach them an important lesson about the presence of foolish people in positions of power.

Keeping track of what URLs people are hitting is trivial on any application server.

That presupposes not just that ApplyYourself is in any way competent (evidence points to dubious), but that they are at all communicative with the admissions grunts.
