i don't see why not. if it was juried, and you were a judge, it's a conflict. however because it lists the entries in order, being the first one would give you an advantage to lazy people, so maybe enter it in the middle. however again, when a contest is confusing i tend to look at what the op put in to get an idea of what the heck they want.
it's only wrong to put your things in, then disqualify everyone else. i've seen people do that.
