There are two sides to every story, which is why I wanted to see your original post.

While I do believe the lady exaggerated quite a bit in her posting, I do have a couple of issues regarding yours.

Issue number one, is it's not that difficult to find a rodent supplier without posting an ad on Craigslist. Sadly, people are naturally going to have problems with that post, even though your intentions are clear. (IMO adding the photo was also unnecessary)

Issue number two, is that it doesn't appear that you own any snakes that are able to consume the large prey items you are requesting.

You were completely within your right to post an ad, but in my opinion you could accomplish the same goal without doing so.
