Most women like it if the review of them is perfect. It gets them business. When the review is less than perfect the review is less liked. And guess what? Anything even slightly negative will be what's remembered - not the praise.
Surprise - they take it personally. Imagine.
The only time it's to your advantage for someone to know your handle is when you've written a perfect review of her and she wants to know who wrote it.
Otherwise, it's sheer stupidity to pass on your handle. To me, your question was equivalent to asking how many of you are really stupid.
I've been asked a few times if I'm one of you - or if I've written reviews. It's on their minds. Further, they talk - in groups. If one knows, it's a safe bet that others will know.
The result, if you go this route, is to get a massage more by the book.
Now, if any of you have it figured out how it's to your advantage to have them all know who you are when you write your reviews, more power to you.
But if any of you are card players, you know you are at a disadvantage if you are the only player that doesn't keep your cards face down.
