If you ever posted a sickle-and-hammer to the web, visible to the Hungarian public -- distributing it -- then you possibly could be fined for it. If you visit Hungary and you got fined, would you consider it just? Here's the Hungarian Criminal Code article in question:

Article 335(1). Any person who a) distributes; b) uses in public; c) exhibits in public; a swastika, the SS sign, an arrow-cross, a hammer and sickle, a five-pointed red star or a symbol depicting the above, – unless a graver crime is realised – commits a misdemeanour, and shall be liable to punishment with a fine. (2) The person who uses a symbol of despotism for the purposes of the dissemination of knowledge, education, science, or art, or with the purpose of information about the events of history or the present time shall not be punishable. (3) The provisions of subsections (1) and (2) do not extend to the official symbols of states in force.
