If the contest doesn't specify how often you may enter then, I see no problem with it. It may not be exactly ethical, and really shitting thing to do if you were an adult in what appears to be a kids contest. If the contest doesn't specify the number of entries go for it, you've done nothing wrong.

If the contest did specify and the kid stuffed the ballot that's pretty low, but at least a kid who was super dedicated and excited got it. I wouldn't do it but I would definitely shrug it off if that were the case. I would be angry as hell if an adult did it, or encouraged a kid to do it.

There is a lot of things in life that aren't explicitly disallowed but make you a selfish asshole if you do them. If a kid was brought up properly by there parent and can assess right or wrong and then sees other kids being unethical and then winning, it only promotes negative behavior.

Its incredibly low to prevent others from entering by taking all the forms.
