I don't have a problem with that as she is paying her clients for doing her marketing for her. I think prospective clients should be extremely sceptical about all feedback and reports on AW and cautious about trusting reports on other sites too. In amongst some honest reports there are a lot of fan boy reports, overly generous reports, reports written by the WG herself/her agency/her mates/her parlour etc. Few reports are written for the benefit of other prospective clients. Most are done as a favour for the WG. (I have done both types of report myself)
When assessing reports I typically look to see if that client has written a bad report on someone. If they haven't then I assume that their reports are going to be unrealistic and overly generous. If they have a history of reporting on poor experiences then I am far more likely to believe any enthusiastic reviews they have written.
