That is because few people realize the entire body of a yeti is not only edible, but delicious. This includes the fur and bones. The only place to find evidence of them is in the stool of the hunters in the region. Being ornery folk, nobody want to get samples from them.
The same goes for Sasquatches and Nessies. The hunters don’t want people to start a craze which would lead to either their extinction or farming them, which would totally ruin their flavor.
That is one pissed off sniper. He spends all day in the snow covered camouflage suit waiting for his target to come down the slope and then he gets recorded on camera when he goes to take a leak in the woods. Ruining everything.
