I put the ad up, and through it, we met up with a couple who were recently married. They sent me pics of themselves with their snakes, showing their cages (tubs, proper setups, Helix t-stats with FW, etc.) They adopted our corn snake and more recently, the BP.. they were "repeat customers" who would probably adopt or buy from us again. They were actually cool people and we ended up talking about herps and tattoos for a few hours.
Quite honestly, whether I am selling a morph BP on my website, or adopting-out on CL, I screen the people who want to buy or adopt. There are many people that wholesale their normals to pet stores and I don't see CL as anything worse than that.
Now I know that CL does not allow "selling." I don't go against this by, for example, advertising Pastels for $100 or something like that. I only adopted out normal males on there that were/are pet-quality snakes, and I saw and see CL as a great venue to meet people that almost lived in our own backyard, but who we never would have met otherwise.
