You are right. We will edit the rules. The law states visual depictions so we will limit it to that.
for reference: Sec. 1466A. Obscene visual representations of the sexual abuse of children (a) IN GENERAL- Any person who, in a circumstance described in subsection (d), knowingly produces, distributes, receives, or possesses with intent to distribute, a visual depiction of any kind, including a drawing, cartoon, sculpture, or painting, that– (1)(A) depicts a minor engaging in sexually explicit conduct; and (B) is obscene; or (2)(A) depicts an image that is, or appears to be, of a minor engaging in graphic bestiality, sadistic or masochistic abuse, or sexual intercourse, including genital-genital, oral-genital, anal-genital, or oral-anal, whether between persons of the same or opposite sex; and (B) lacks serious literary, artistic, political, or scientific value; or attempts or conspires to do so, shall be subject to the penalties provided in section 2252A(b)(1), including the penalties provided for cases involving a prior conviction.
