I don't know the actual veracity of a place like this, but I'm making a mental note of what's here anyway, but this place seems to have a thread on her, and a few other threads on that same subboard mention her here and there:

A summation:
-Part of an idol group that broke apart years ago
-Allegedly she scammed some guy into paying for her to come to Japan in the first place under the pretense of hooking up, but she blueballed the guy and he ended up throwing her under the bus in several idol/talent circles a bit before her idol group broke apart (?)
-She had an embarrassing solo talent run for a while there
-She constantly whined about her struggles and lashed out at both her fellow idols and her fans alike
And probably some other shit I'm not immediately remembering as I'm typing this.
Bearing in mind I'm taking all of this with a grain of salt, but I still think it's worth considering unless proven completely fake.
There's also this interview over here.
