You would be stupid to post an assignment on something as well known as rentacoder. I've ad professors who have mentioned finding their assignments on there so they are well aware.
But there are people that stupid and the need to check such sites is just one more bit of overhead.
Hmmm, I suppose it's unfortunate that a final exam does not lend itself to requiring the use of a computer to demonstrate that you truly can program your way out of a paper bag.
