I was asked the first time I met one SP where I had got her details from, and if I use UKP or UKE.
At the time I was only aware of AW and vivastreet, and vivastreet looked a bit fishy.
That question led to me finding this place ( and UKE).
So asking me may have backfired from her perspective, but from mine I know, or have at least thought about, a lot of things that I wasn't aware of. That had never occured to me.
I've never mentioned reviews to any SP, they've not mentioned them to me. At some point I may do so, re AW reviews as I may want a few feedback as some SPs seem to require them.
I can't see that any good could come from informing an SP of a review on here, even if it's good.
Could look bad, manipulative, and you can never tell how someone will react to an honest review of themselves.
