I've notified those in charge of the site. Thanks for pointing that out!
Thanks, looks fixed now.
It is now located at http://ai-contest.com/ although it hasn't been updated for the latest challenge (Ants, which hasn't started yet).
All the YouTube vids are broken because the account has been closed. How odd.
hacked, or monetized?
In my experience, most universities forbid the monetization of sites that they host.
I'm going with hacked.
It seems likely that someone involved with the contest is trying to use it for free advertising. Look at the "About" page on that flash app, the person apparently lives in Waterloo, and his email has "uwaterloo" in it.
