I am producing far more dart frogs than I am snakes at the moment. And yes. I have refused to sell to someone.

I am the kind of seller that is doing just as much research on an individual as if I were a buyer. Things like, parasites in their collection, "mysterious" deaths, poor housing/husbandry, etc. All of which are very easy to find record of on a public forum.

I have a list of people that I will not buy from or sell to.
