Its not saying that i would TRY to REHOME ANY snakes!!!!!
Wendy, everyone knows that you are a "victim" (although you do not appear to feel that way), or simply a buyer of a "pet" (that happened to be sick), and that you are not in a business to sell snakes.
Other aspects aside...If Nick did not disclose, to you, that the Poss. Super arrived in the same bag as a sick snake ... that, in itself, is poor ethics &/or a poor business practice.
I think people are just "taken aback" that you do not feel victimized &/or just view one or two, of Nick's actions, as an excusable "mistake" (although, in his own words, Nick has shown that he would, knowingly, sell an ill snake). As far as I am concerned, how you feel, toward Nick, is your choice and is neither here nor there.
However, since you have received more snakes from Nick, I hope that you keep the intent to possess them for the rest of their lives but,... should something happen (where you absolutely cannot keep them),... either give full disclosure, to a potential buyer/recipient, OR, if, after full disclosure, they cannot be sold or given away, euthanize them (esp. if they cannot be, 100%, proven IBD free).
As for Nick and Kevin ... both of them ~are~ in the business, to buy/sell snakes, and it is ~them~ that need to take certain measures but that, apparently, people are doubting would do the right thing.
