The Hungarian Two-tailed Dog Party closely involved in the campaign during the October 2016 migrant quota referendum, mocking the government's anti-immigrant messages and phrases. The party spent €100,000 of voluntary donation from 4,000 people for their posters with satirical slogans, such as "Did you know there's a war in Syria?", "Did you know one million Hungarians want to emigrate to Europe?", "Did you know? The perpetrators in most corruption cases are politicians" and "Did you know? During the Olympics, the biggest danger to Hungarian participants came from foreign competitors". Party leader Gergely Kovács told BBC News that "[...] What we can do is appeal to the millions in Hungary who are upset by the government campaign. We want them to know they are not alone". Thus the party asked the people to vote invalidly. Eventually, 6% of the voters cast a spoiled ballot.
