Is this a standard 2257 disclaimer? I don't recall ever seeing this particular wording, but I could be wrong.
Both sites have this same paragraph on their legal pages:
"
In compliance with the Federal Labeling and Record-Keeping Law (also known as 18 U.S.C. 2257), all models located within our domain were 18 years of age or older during the time of photography. All models proof of age is held by the custodian of records, which is listed below organized by producer. All content and images are in full compliance with the requirements of 18 U.S.C. 2257 and associated regulations."
