Names are taken off the site for many various reasons.

Most of the time, the name itself isn't used. Katana was listed for some time, until it was determined that it was not used as a name in Japan. It's a site based on etymology, so if the name's history doesn't ring true, or it isn't used, or the meaning is found to be incorrect, it's either changed or deleted. The entry for Orion used to state only that it meant urine, and Amaya was defined as meaning night rain. Both have changed. Etymology isn't a set science such as chemistry, it's a constantly shifting science as new facts are discovered. I suspect Aviana was taken off because it was not used, and was thought to be a modern invention.
