The poll results will be checked through a number of sources. In addition, it is against the rule to show anyone or even tell anyone about the level in a way that would allow them to know which one is your's. Anyone who cheats on voting will be disqualified from voting. Anyone who obviously cheats in voting who submitted a level will be disqualified from the contest, and possibly publically humiliated. This is reason enough not to cheat.
