Yes Dani has posted about this before, she no longer has access to the AW hidden feedback system because she researched it for someone. I expect you can find it if you trawl through the back posts on here...
When another WG confirmed that I had some malicious hidden notes, I wrote to AW, who promised to remove it, and asked the name of the WG who had told me.
I didn't give them the name, not wanting to get her into trouble; apparently AW didn't remove the feedback, only downgraded it from "dangerous" to "timewaster" :-(
