Authorities in Moscow have banned billboards containing QR codes after allies of jailed Kremlin critic Alexei Navalny used the matrix barcodes to conceal their newly launched anti-Putin campaign ahead of the 2024 presidential election. Navalny on Thursday urged supporters to vote for any candidate besides Vladimir Putin during the race, which is scheduled to take place on March 15-17.On Friday, the 71-year-old Putin officially announced his bid to run for a fifth term.Navalny’s team launched the website neputin.org (translated from Russian as “Not Putin”), which calls on Russians to convince others to vote against Putin.The website was accessible via a QR codedisplayed on billboards across Russia that read: “Russia.

Happy New Year.”Municipal workers promptlytook down the billboards, according to the independent news outlet Sota. Moscow's city government circulated a letter among ad distributors on Thursday, Dec.
