For instance, if the first TER review for a gal lists height as 5'7" and the next 8 reviews list her as 5'2" does that item change over time?

So, the first description of the provider sticks? I know the provider can fill in & change rates, what else can they write in their profile?

From what I've read here both providers & hobbyists can request a change on a profile by submitting a Problem Report. Often whatever change submitted must be proven, through photos, I guess. Often those submittals are rejected due to insufficient info or evidence. It's up to whichever moderator sees the report to determine whether it warrants the change. If you get it approved you also get a couple of VIP days.  

The very first review/profile shouldn't be the end all of descriptions.  Subsequent reviews always ask for profile descriptions; so they should be averaged so an accurate profile can evolve. If TER can use a computer program average Looks & Performance, they certainly can do that easily.

...if someone files a Problem Report pointing out that the next 8 reviewers said in their reviews that her height was different, TER will change her profile.  That would be considered acceptable proof.

agree!

There are other forms of proof for a height change that can be used in a problem report also. for example, what height does she have listed on her website, or ad, or p411 profile etc.

Photos might be useful for things such as tattoos or piercings (ie profile says none, but photos clearly show them), hair length and color, breast size and implants. Unless you had a police record type photo where she is standing in front of a wall with height measurements, a photo would not be proof for height. For height proof you could use her height mentioned in an add, website, or verification site profile, or if her height was mentioned in subsequent reviews, as being considerably different than the profile height.

It's not just about height -- Think of all the profile info: Age, implants, breasts appearance (which is a misnomer; you can only FEEL this item,) ethnicity, tattoos, etc. And then there's the services offered (again a misrepresentation,) we all know providers that at first only gave CBJ's and in time was willing to BBBJ -- I don't think those items change over time.
