I suspect it's a mere challenge for the "troll" to see if they can beat the system. If not, they'll try harder until they can. The more challenge the more rewarding it is, thus the harder they try and eventually succeed unless it's impossible (in which case they figure it out and quit trying).

It's really the sincerest form of hacker spirit which manifests itself this way. Why? Because internet^H^H^H^H^H^H^H^H Hitler.

Edit: Well, I didn't quite address the art part but still.

I think the troll's motivation is closer to breaking a seemingly useless system to waste the time of those who think its important.

You can argue against something, or show it to be unworkable.
