Corn has always been hunted over but not like now. Now every single small land parcel has a feeder on it and no one cares about what they shoot because they just pulled it across the line from some other piece of property. Cell cameras are not the same as other cameras. I know a lot of instances where a buck moves into an area for a couple days because of a hot doe. Few years ago most people would not have known that buck had been there until they pulled the card on weekend.....now, camera goes off and said person is on the way and usually can kill that deer. Not breaking any laws but it is making a big difference.
Bingo… I personally know of three 5 year old deer that were killed last year that were killed with the six of corn and cell cams. Every buck was worn down from the rut and showed up at a corn pile in the morning. The guys monitoring the corn piles made arrangements to get off early (if they were working that day) and went that afternoon and killed him. Like you say, had it been a traditional camera they likely wouldn’t have killed any of them.
