I have been a member on Adult Folio for a while and have found it to be an excellent site for my modelling experience. I have never had any inappropriate messages or comments. I have met some really genuine and friendly photographers and enjoyed subsequent shoots. It is of course good to have contact with them in my opinion via phone to discuss a forthcoming shoot to make sure we both set the content and any limits and also to get an idea of the photographers friendliness and ideas.
I do get a lot of views from over seas and perhaps a UK only filter could be added.
But overall a really good site.

Excellent site, well-organized, efficient, and very professional staff. The subscription fee for all the services is very reasonable and affordable. I highly recommend it.
