Private Vocaloids don't get very popular such was Akikoloid-chan's fate. So you can pretty much say if their private... Give them 2 years tops and we'll have forgotten about them. Most skipped over Akikoloid-chan the moment they found out she was private.

Needless to say, the moment you declare a vocaloid "private" you've killed your project.
