A while back a provider posted an ad that included the following offer: "The 2 hour pamper special is usually 500 but for TER members I am dropping it to 450 and if you are a VIP with reviews, let me know and I may even go a little lower! *wink*."  I've seen this kind of ad before and i'm sure that the provider meant no harm.  By identifying TER members she can verify more easily and in a sense keep it all in the community.  Nevertheless, it seems dubious to me: any review (of an escort, a restaurant, a book, etc) depends on candor and thus on initial anonymity.  While I'm sure this provider would never intentionally pressure a client into a positive review, it seems obvious that a client could feel less comfortable producing a negative review once he has identified himself to her.  Further, once anonymity is lost not only is the review compromised but the client may be as well.  In the case of a negative review it is possible that the provider may be inclined to respond or, worse, retaliate.  I say this not because i think that many providers would do so, but I've read some angry posts from providers steamed about an unfair review, etc.  (It's worth noting that the provider who posted the above ad ended up in a board-dispute with a displeased would-be client, scolding him for airing dirty laundry.)  I recognize that sometimes hobbyists use reviews unfairly: to denigrate providers for personal reasons.  Still, that seems to me the tradeoff for having candid reviews.  
  If reviewers want to identify themselves to providers after the fact, usually in a thanksful, celebratory review, that's fine.  But don't give up so much freedom in advance.
   I repeat that I do NOT mean to suggest that providers regularly attempt to monitor, influence, or "out" reviewers, and certainly not that they would use personal information against their critics.  I mean only that TER reviewers should maintain their anonymity, for their own sake and for the sake of their reviews.
