Moscow residents say they have found that the only way to get the council to clear snow is to write the name of opposition leader Alexei Navalny on it.
One user said the move prompted immediate reaction and that council workers removed the graffiti "within hours".
Mr Navalny is Russia's best-known critic of President Vladimir Putin, and state media never mention him by name.
President Putin famously refuses to call Mr Navalny by his name, usually referring to him as "that person" when asked about him.
Moscow has seen huge snowdrifts pile this year, and has experienced some of the heaviest snowfall in decades.

He nearly lost his sight in one eye after being attacked with an antiseptic green dye in Moscow last year. »
