As a former member of Charter 77,[1] Cibulka was imprisoned multiple times during Communist rule in Czechoslovakia.
Prior to the Velvet Revolution in 1989, Cibulka had been arrested three times, and spent a total of four years in prison for distributing non-official cultural and musical material.
[citation needed] In the early 1990s, Cibulka published material from still-classified StB archives, containing lists of tens of thousands names of people with connections to the secret services.
Cibulka published an online political journal entitled "Uncensored News" (Czech: Necenzurované Noviny).
[citation needed] He is also the founder and leader of a tiny political party, the Right Bloc (Czech: Pravý blok).
