Question about possible cheating in Survivor

I did not want to clutter the other Survivor threads with a side question, so I decided to start a new one.

While watching the last immunity challenge last night where the contestants were blindfolded, I was thinking, what is stopping a player from throwing the extra necklaces at a station on the ground to prevent others from finding them, would that be allowed or would it be considered cheating?

I’m pretty sure that would be considered cheating. There are a lot of rules they don’t bother telling us about every game. I’m sure that’s one of them.
