Yelp acquired Cityvox in October of 2014.
We’ve incorporated most of the reviews from Cityvox into Yelp. If you posted reviews to Cityvox, you can attach them to your Yelp account (if you don't have an account, you'll need to sign up).
If you don’t want your Cityvox reviews to be on Yelp, please contact our Support team. Be sure to include your Cityvox username so we can handle your request and remove any of the reviews you originally posted on Cityvox.
