From their letter to us:

When choosing your domain name and email address, you cannot use company names such as Trilogy, HealthyPetNet and/or brand names such as Life’s Abundance, Sealogix and Clay Essentials, etc. Also, you cannot use misspellings of company and/or brand names such as sealogics.com and you cannot use variations of company and/or brand names such as essentialsclay.com, etc. Disregarding the above guidelines creates an unfair advantage and it is a violation of our compliance guidelines.
