"…This chatroom (KIK) is expressly restricted in its user terms as being limited to those over 17 years of age. It cannot therefore be asserted that the [appellant] either began accessing the internet in general or this app in particular in order to engage in contact with minors. The [appellant] was not initially drawn to access the profiles which he accessed from any belief in the professed age, or any apparent vulnerability of any of profiles in question. When he engaged in the conversations concerned he in no way engaged in any coercive dialogue, and at the time during all relevant conversations and exchanges believed the persons in question were minors."
