[Rubber Duck]

Selling of non-primary terms is not limited to lists.

Most of the Flippers here are comparatively new to the game. Many of the names that are offered are not primary terms. This is particularly true of Japanese where there are multiple scripts and many alternatives.

Use your common sense. Simply banging these terms into a search engine will tell whether the terms have a common usage. If you use the local version of a search engine you should also be able to gauge the advertising demand for the keyword.

I must admit I would probably have bought a list from Alpha, if I had felt the need. There are few professionals of his calibre in this game. The reputation of the person you are dealing with is not something to be lightly dismissed.
