To understand the Act, I recommend reading it. Until we have case
law, it is unclear how this may be applied, but the best source is the
act and the U.S. Code.
This is the latest version I was able to find.
This is the section where the act adds a whole set of subsections dealing with interactive computer services. The key provision seems to be in subsection (d), which prohibits use of an interactive computer service to send or display to a specific minor "any comment, request, suggestion, proposal, image, or other communication that, in context, depicts or describes, in terms patently offensive as measured by contemporary community standards, sexual or excretory activities or organs, regardless of whether the user of such service placed the call or initiated the communication..."
This is where the act adds interactive computer service to the list of ways you cannot transport "obscene, lewd, lascivious, or filthy" matter. This is also where "any drug, medicine, article, or thing designed, adapted, or intended for producing abortion..." and all the descriptions of such matters are banned from transport or importation.
This is where the act adds interactive computer service to the list of ways you cannot transport "obscene, lewd, lascivious, or filthy" matter for the purpose of sale or distribution.
This is where the act raises the imprisonment period from five to ten years if the person being coerced or enticed into prostitution or illegal sexual acts is a minor. It also adds "attempts" to coerce or entice a minor.
