I think the way the site links together "35 reviews for Amber" for all the AW girls is great. But it would be great if we had a similar thing for agency girls, and agencies themselves.
I think some respondents to this have missed the question. The problem, as I see it is this (it may get techie). AW has a unique database user id for each profile. This id can be used for linking numerous profiles for the profile holder together, which is why we must use the id in our reviews.
The system comes unstuck when a WG sells/gives her profile to a new girl. However AW is so well used that the UKP community picks up profile swaps pdq (usually).
Other sites, e.g. agencies, do not have unique ids. The url might be e.g. myescortagency.com/emma. The whole text string could, in theory, serve as the identifier to link to a SP ID and therefore used to link reviews together.
However if emma left said agency, the website manager might just assign the next, or a future girl, to to the name emma. The new Emma would then inherit the previous one's reviews. This might not be picked up as readily as with AW due to the lower level of awareness.
It is a shame we can only do this review linking for AW girls and not say vivastreet and other sites. I think it could be done as I describe, but one caveat might be a complusory picture or more scraped off the girls site to help identify changes to the girls at a specific url
If anyone were willing to have a techie discussion on this we could create an off-topic RFC. It would require admin input, however, since only he knows what is possible to do with the backend tables. I'm sure volunteer php coders can be found
