Thanks lexcorp. If you check out Zillow on the web you will find that it is much, much more than a house flipping business. It is one of the largest real estate companies in the US. (https://en.wikipedia.org/wiki/Zillow https://www.kylehandy.com/blog/learn/zillow-vs-realtor/) The following link show that it actively competes with RMA by providing a variety of marketing tools to agents including agent reviews.

RMA collects and combines agent reviews from Zillow and other sources on the RMA platform.
The US RMA website states: https://www.ratemyagent.com/blog/post/maximizing-the-power-of-online-reviews
"Your online reviews are the most powerful marketing tool you have – but you don’t know WHERE people are searching for them. They could be searching Facebook, LinkedIn, Zillow, your own website, Google or Ratemyagent.com. You just don’t know – so your reviews have to reach every possible online avenue."
