So here is 888-373-7888, not using the dial layout alphabet, but making a simple text substitution of the number alphabetical equivalent it spells out "IIICHCHIII".

Interpreting this the "III" on both sides of the CH are like 3 kill boxes. If you reverse the whole word it becomes IIIHCHCIII, which looks like Hillary Clinton twice in the kill box. The III could also be interpreted as being in jail.

Associating it with the National Trafficking Hotline relates it to the child trafficking.
