Mortgage brokers, mortgage agents, and mortgage lending

About a week ago in Colorado , Erin Toll, the new director of Denver Real Estate Commission began doing an investigation of appraisers that were overvaluing homes. I read yesterday that she is presenting details of her ongoing investigation. She has already recommended  record fines as well as the revocation of licenses of several appraisers for their work in Denver and Pueblo areas. Seems as when properties are overvalued everyone gets hurt. One attorney commented that Ms. Toll seems overzealous and is coming down to hard on the appraisers to send a message to the industry. My question would be how long have they been doing it and getting away with it? This should not be happening.
