The slogan "Putler Kaput!" -- a play on words combining Putin and Hitler -- was found by the prosecutor's office to be offensive to Putin and has been banned from use at public gatherings and meetings.
Of late, Vladivostok has seen some of Russia's biggest antigovernment protests over the economy. (Read what Brian Whitmore has to say over at The Power Vertical on whether Russia's social contract is breaking down.)
Vladivostok Communist Party leader Vladimir Bespalov told RFE/RL that he does not understand the ban, adding that to challenge authorities one must use strong words.
