Let me be the first to recommend producers NOT to do this.
Physical viewable looks trump any body stats.
Seems like an easy way for those with less than honorable intentions to narrow their search results for models by having provided stats.
When it pertains to persons personally identifyable information, yes.
Are you going to take the models word or will an annual weigh and measure be required?
Generally women do not have ages, measurements, weights, or shoe sizes as far as even their very best friends are concerned, so forget about truthful statistics.
Wrong
As I'm sure you know, model network sites have this info listed to search by, which some people would love to get so that they can narrow down their searches and hopefully find non-regular / one-off performers in videos who may not be going by their fetish video pseudym and bother / pester them.
There is absolutely no reason to know models actual age, weight, dress size, exact height, where they are from, etc. unless you plan to use it in search for them to potentially contact / pester. None of this has bearing on actual looks.
