I have it from a reliable source that Zillow also causes hemroids and oral herpes. It is also though they were involved in the Lindberg baby kidnap/murder. All the details are on that other message board too - well worth reading but unfortunately the shorts here have the creditability of rabid ferrets!
Zillow sure causes headaches and unnecessary stress for 10 million homeowners whose homes are inflicted with erroneous and unwanted zestimates and zillows absolute refusal to correct or delete their incorrect valuation. Shame the SEC doesn't investigate that as well.
