Nothing to figure out here, hunting over bait is not fair chase, even where it's legal. Your neighbors who are setting out this bounty may even be breaking the law, some areas prohibit feeding wildlife out of concern for disease transmission, so you'd be best served not hunting there at all. If it is, in fact, illegal to feed game where you live then you're duty and honor bound to report them. Ethics can be a hard act to follow, but they're usually right.
