I had a hunch the Russian Federation listing of sanctioned US Citizens had deeper meaning so I started digging on some of the names listed as "US Citizen" - To my amazement, the first three I looked at were involved in the death or abuse of children.
Could this list be CHILD SEX TRAFFICKERS and SATANIC CULTISTS?
