There are these fellows that are displeased with the alleged inner workings of their governments. They then place lots of posters onto many places of public gatherings details of their grievances, which find their way into worldwide circulations, other forks from the farthest ends of the earth happen to get their hands onto them.
Conspiracy theorists thrive to expose alleged government secret operations and eventually spread all over the world and anybody who can gets their hands onto them believes them to be true. The visitors’ nations get to learn the language of the hosts, watch their politics and get to know more about them than the host knows about them.
Where there is lack of knowledge among the people, superstition takes a stronghold.
