Trans 500 could be vulnerable under 18 U. S. C. §2252A, which provides:

"(3) knowingly--
. . . . .
"(B) advertises, promotes, presents, distributes, or solicits through the mails, or in interstate or foreign commerce by any means, including by computer, any material or purported material in a manner that reflects the belief, or that is intended to cause another to believe, that the material or purported material is, or contains--
"(i) an obscene visual depiction of a minor engaging in sexually explicit conduct; or
"(ii) a visual depiction of an actual minor engaging in sexually explicit conduct,
. . . . .
"shall be punished as provided in subsection (b)." §2252A(a)(3)(B) (2000 ed., Supp. V).
Section 2256(2)(A) defines "sexually explicit conduct" as
"actual or simulated--
"(i) sexual intercourse, including genital-genital, oral-genital, anal-genital, or oral-anal, whether between persons of the same or opposite sex;
"(ii) bestiality;
"(iii) masturbation;
"(iv) sadistic or masochistic abuse; or
"(v) lascivious exhibition of the genitals or pubic area of any person."
Violation of §2252A(a)(3)(B) incurs a minimum sentence of 5 years imprisonment and a maximum of 20 years. 18 U. S. C. §2252A(b)(1).
The Supreme Court upheld this statute in 2008 in United States v. Williams,
