I thought the Chaturbate TOS was quite clear on this.
Section II: The Platform:
A) The Platform (as defined below) is an online platform providing social networking capabilities including both a text and video chat service whereby individuals accessing the Platform (each a "Community Member") may create and share with other Community Members online audio, video, interactive, and live content which may include, at the providing Community Member’s election, content of an adult nature. Community Members, whether or not their account is capable of receiving tokens, are free to broadcast their live streaming video through the Platform, subject to the minimal restrictions set forth in these Terms, which restrictions have been put in place to comply with applicable law, community standards, and for the safety of the Community Members.
Section III: Introduction and Description of Services
A) When you access the Platform, you understand that you may see graphic depictions of nudity, exposed genitals and persons engaged in explicit sexual activity consisting of heterosexual, bi-sexual, homosexual and fetish activities, as well as sexual acts involving more than 2 individuals. By accessing and/or using the Platform, you expressly acknowledge that you wish to see such materials.
Section VI. Content:
A) Obligations Under 18 U.S.C. §2257. You should be aware that, pursuant to United States federal law, any visual depictions that you post, share or perform on or through the Platform which portray "actual sexually explicit conduct", "depictions of the genitals or pubic area", or "simulated sexually explicit activity", as those terms are defined in 18 U.S.C. §2256(2)(A)(i)-(iv) and §2257A, require that you maintain the records listed under 18 U.S.C. §2257, and any such postings must contain a "18 U.S.C. §2257 Record-Keeping Requirements Compliance Statement." Your failure to comply with the provisions of 18 U.S.C. §2257 may make you subject to criminal and civil prosecution for the violation of federal law.
It does not matter if the person looks obviously overage. The law states that all performers must be age-verified and Chaturbate must have all of their information on record. This is the same for every site of an adult nature, and Chaturbate spells it out quite clearly, over and over again, that they are an adult website catering to adult themes. Therefore, any performer looking to take off their clothes MUST be age-verified and records of this must be kept. And rather than take people's word for such a thing (It's like people will lie on the internet or something!), they need those records for their own protection. Anyone who tries to cam/perform on an adult site without being ID verified is breaking one of the biggest Federal porn laws on the books. Maybe once upon a time they didn't apply these rules as strictly, but big sites can't get away with that anymore.
