Kinda contradict yourself, dont cut into the wild population unless it is something cool, but shame on them for picking that up?
Wild caught snakes unless a visual difference fetch a far lower price than captive bred, what kind of well would they be poisoning, besides their reputation, lying gets you far. Actually the only ones I personally know to buy wild caught are Breeders trying to meet wholesale demand. Of course if anything dinker worthy came they would keep it, but i would assume it to be quite rare.
