Roskomnadzor is just an executive body, it follows the existing law and has no power to initiate legislation or the right to "prohibit" something.
So I can do anything and they can't stop me directly. The only thing what they can do is
ask me to delete the picture.
Of course I'll say them "get the fuck out of me" and then they'll initiate a lawsuit on this case. And this lawsuit will end with a failure, because no judge will take it seriously. 
It doesn't look like the courts will take this lightly, the decision to censor memes comes directly after a Moscow court already ordered a site to take down memes:
Russian censors have determined that one of the most popular forms of Internet meme is illegal. According to Roskomnadzor, the Kremlin’s media watchdog, it’s now against the law to use celebrities’ photographs in a meme, “when the image has nothing to do with the celebrity’s personality.”
The new policy comes on the heels of a court decision in Moscow, where a judge ruled that a particular photo meme violates the privacy of Russian singer Valeri Syutkin. The court’s decision targets an article on Lurkmore, a popular Wikipedia-style Russian website that focuses on Internet subcultures and memes.
The court ordered Lurkmore remove controversial meme "BBPE" with Syutkin
Moscow, on 7 April. According to the decision of the Meshchansky Court of Moscow common network meme "BBPE" with photographs of the Russian singer Valery Syutkina obscene and signature must be removed from the pages of the online encyclopedia "Lurkomore» (Lurkmore). Thus the Court granted the petition Roskomnadzora, who represented the singer in court.
Over the next 30 days Lurkmore must remove meme with a portrait or Syutkin Roscomnadzor make resource page in a single register of banned information (which it does, however, regularly, on different occasions).
Photo by Valery Syutkina with an appropriate inscription for several years used the Internet meme BBPE, "Beat a woman by ... (person)", probably due to the fact that intelligent and cheerful person Syutkina better than others opposed to the absurd slogan that allows you to instantly achieve a comic effect.
Earlier in December Meshchansky Court in Moscow refused Roskomnadzor in considering a claim for blacklisted page online resource "Lurkomore» (Lurkmore) to offend Valery Syutkina meme known in abbreviated form as "BBPE", as applied to him "wrong applicant ".
According to the creator of "Lurkomorya" scandalous picture two years older than the site itself. Directly involved in the developments took my mother a singer: she was found that the image of his face "used in bad faith."
Site Lurkmore positions itself as an online encyclopedia of contemporary culture, telling, including the history of the origins of the various memes. The Internet provides the following description of the resource: "Lurkomore» (Lurkmore) - informal, unformatted, frivolous and humorous online encyclopedia, positioning itself as the "Encyclopedia of modern culture, folklore and subcultures, as well as everything else."
Your assertions no court will take this seriously is undermined by the fact that they already are.
