If you play a game for an extended period (as you might do while idly surfing), then attempt to submit a score, it will say something to the effect of unauthorized access, resulting in your high score being lost. Pretty well sucks if you get a good score and it gets canned.
I assume this is a timeout feature, but can the upper limit be extended?
