I for one, welcome our overlords in rock, paper and scissors :)

Humans do not fail in simple problems like the one I illustrated. Of course there are situations in which humans fail to use the proper context. But robots can not solve a single one without specific instructions about their environment.

I think not... It's not even mentioned in the article See http://en.wikipedia.org/wiki/Frame_problem or an illustation: "The philosopher Daniel Dennett asks us to imagine a robot designed to fetch a spare battery from a room that also contained a time bomb. Version 1 saw that the battery was on a wagon and that if it pulled the wagon out of the room, the battery would come with it. Unfortunately, the bomb was also on the wagon, and the robot failed to deduce that pulling the wagon out brought the bomb out, too. Version 2 was programmed to consider all the side effects of its actions. It had just finished computing that pulling the wagon would not change the color of the room's walls and was proving that the wheels would turn more revolutions than there are wheels on the wagon, when the bomb went off. Version 3 was programmed to distinguish between relevant implications and irrelevant ones. It sat there cranking out millions of implications and putting all the relevant ones on a list of facts to consider and all the irrelevant ones on a list of facts to ignore, as the bomb ticked away."

I would agree if the students were required to enter a discussion about the subject on a single page. However, this is just trolling, the students won't look back and just write 10 200-word posts and post them on various websites. I'd expect the college to have a reasoning like yours, however, it only works in their is an actual involved discussion.

That is why I use DenyHosts, it shares the ip's of brute force addresses among its users. That way you don't get attacked by all the bots in the botnet. If you use a rule like 3 strike-out to it you can even contribute and help others before the masses of zombies are on their doorstep.
