I found out now, there is a comedy conspiracy theory "Delaware does not exist" https://delawareness.tumblr.com/
It is similar to "Acre não existe" in Brazil. Acre is a small state in the middle of the Amazon forest. It is the home state of Marina Silva, who was at the third place in the presidential elections of 2010 and 2014. But Acre does not exist.
In Germany, there is the Bielefeld does not exist.
In Italy, we have Molise does not exist.
(Molise is a small region who was created in 1963 that is after all the other ones)
