From what I've read there's never been an issue with the snakes themselves.
But if you read through the threads at fauna, he single handedly tried to crash the ball python market for personal vengeance. He is a scum bag. Period. Only in it for all of the wrong reasons.
Sure you can get some nice snakes for cheap, but by doing so you're just supporting sleaze. I'd rather pay more money knowing its going to a good person or business who cares about the animals and the hobby.
