1) There are more cheats than that. They are features. The reputation isn't a matter of national security. It is just hidden from casual viewing until you vote the node in a limited attempt to reduce "bandwagon voting" (though I'm getting the impression that seeing the reputation before hand could lead to a lot more "voting against the rep" which would level out reps rather than widening the distribution).
2) No, sorry, you got that wrong. When you run out of votes the voting "buttons" disappear but the reputations of any nodes that you've already voted on are still visible (and I actually stayed up late getting rid of all of my votes to verify that this hasn't changed since the last time I used up all of my votes some dark ages ago q-: ).
