(CNN) -- Russian efforts to meddle in American politics did not end at Facebook and Twitter. A CNN investigation of a Russian-linked account shows its tentacles extended to YouTube, Tumblr and even Pokémon Go.
The donotshoot.us website in turn links to a Tumblr account. In July 2016, this Tumblr account announced a contest encouraging readers to play Pokémon Go, the augmented reality game in which users go out into the real world and use their phones to find and "train" Pokémon characters.
Specifically, the Don't Shoot Us contest directed readers to go to find and train Pokémon near locations where alleged incidents of police brutality had taken place. Users were instructed to give their Pokémon names corresponding with those of the victims. A post promoting the contest showed a Pokémon named "Eric Garner," for the African-American man who died after being put in a chokehold by a New York Police Department officer.
Winners of the contest would receive Amazon gift cards, the announcement said.
It's unclear what the people behind the contest hoped to accomplish, though it may have been to remind people living near places where these incidents had taken place of what had happened and to upset or anger them.
CNN has not found any evidence that any Pokémon Go users attempted to enter the contest, or whether any of the Amazon Gift Cards that were promised were ever awarded -- or, indeed, whether the people who designed the contest ever had any intention of awarding the prizes.
"It's clear from the images shared with us by CNN that our game assets were appropriated and misused in promotions by third parties without our permission," Niantic, the makers of Pokémon Go, said in a statement provided to CNN.
