I am also not a lawyer, but I am stubborn. What I would do in this situation is to write a response letter saying, "I do not believe your accusations have merit, therefore I will not comply with your demands. I am open to further negotiations, but I will not agree to withdraw any of my own work from publication." Then they would have to make a more reasonable demand, or actually file a lawsuit. In their complaint and summons, they would actually have to make a case, and request some form of relief that the judge could grant. And my answer to it would essentially be this: I deny all claims made by plaintiff. This would be followed by a request for discovery, for all computer access logs wherein Zillow believes that I bypassed their method of preventing those who have not agreed to their terms of service from accessing content via their website. Then I'd let the statutory clock run out on that and move for dismissal. There is a miniscule chance they could prove that she accessed their website at all, much less show that she violated ToS in doing so.
