Depends. Baiting is legal where I hunt in KY. My brother and myself have never baited, been hunting there for a while. The guys that bait around us, have little to no success. Area we hunt is crops, thousands and thousands acres of crops. Baiting has almost no affect on deer. Sure doesn't help see them.
"Depends" is indeed the operative word
In the scenario you describe above, I've seen similar outcomes myself.
Hunting in KY, areas with lots of agriculture, and abundance of food,
and with widespread deer feeding by hunters, the deer simply are drawn much to another bait pile. When everybody (or just many, many) hunts over bait, that baiting seems to lose much of its appear to deer.
Never mind that well-fed, not hungry, deer simply move around less during daylight.
Even in TN areas where deer food is abundant, from lots of agriculture or a massive acorn crop, daytime deer movement can by very low, when the deer are fat & full of food. And as you know, similar happens with fishing. One day the fish feed like crazy, the next day they are fat, full, and not biting anything.
YOU see plenty of deer in KY because you are an accomplished hunter.
Unfortunately for those novices who want to learn how to actually deer "hunt" in KY,
it is actually harder to learn there because of the legalized hunting over bait.
For many, deer hunting has become simply pouring out bags of corn, then taking a shooting position nearby. This is not really "hunting". It's more about "shooting".
