I asked the same question a while back with no answers.  Very intrigued and don't know why I have not seen her.  Love her different look.  She doubles with Cally and shares places with her as well, and I saw Cally, reviewed her, and she is legit, so I am fairly sure Valerie is for real.  Another site had the first and only review as a rip off for a while and that's why I think I never got passed it. But the reviewer since said it was a misunderstanding and the full reviews are good.  If you do see her, post a mini or full.

once upon a time MoCo was very convenient as a place to play and i saw her ad. this was before there were any reviews and i was contemplating TOFFT. i sent 2 emails. this was late 2008 or early 2009, i think. i got no response and moved on. there's been occasional discussion of her at various points which you can find using the search function.

I haven't seen her personally, but she is listed in Date-Check since Dec 08 and was Diamond Member Level Verified there.  So she appears to be legitimate.
