Olena Kurilo became the face of Russia's invasion of Ukraine. Bloodied and bandaged, the 53-year-old teacher said she couldn't believe what had happened to her and her town of Chuhuiv.
Her picture was on the front pages of newspapers across the world.
Over the next few days, Russia's government social media accounts began to post a video claiming that Olena hadn't been injured at all.
"Great photos by the way, they were all over the news," the Russian narrator says.
The video then claims Olena was photographed two days later, uninjured.
"A couple of days later, good for her, not a scratch."
This claim is baseless, the BBC has verified the photo as genuine, as has Reuters. Wild conspiracy theories like these are not uncommon on social media.
But what makes this conspiracy theory so odd is that it was shared by an official Russian government Twitter account - the Russian Mission in Geneva. Two weeks on, the tweet is still live.
The Russian Government has a huge network of official Twitter accounts - the BBC found more than 100 of them. They range from accounts that represent foreign missions or embassies, with a few thousand followers, to accounts with more than a million followers. President Putin has his own account. Many of the accounts are labelled as Russian Government organisations by Twitter.
Yet, while many of these accounts have spread disinformation, Twitter deals with them differently to Russian state media - like RT or Sputnik.
On 28 February, Twitter announced it would prevent tweets from Russian state-affiliated media outlets from being eligible for "amplification" - meaning they wouldn't be recommended in the Home timeline, notifications, and other places on Twitter. But Twitter has confirmed to the BBC that this policy does not include Russian government accounts.
Tim Graham, a social media analyst at QUT Digital Media Research Centre in Australia, describes this as a "loophole" in Twitter's moderation policies which lets the Russian government pump out misinformation.
"It's certainly a blind spot in Twitter's defences against disinformation," he says.
Intrigued by this spider web of Russian government accounts, Mr Graham - who specialises in analysing coordinated activity on social media - decided to investigate further. He analysed 75 Russian government Twitter profiles which, in total, have more than 7 million followers. The accounts have received 30 million likes, been retweeted 36 million times and been replied to 4 million times.
He looked at how many times each Twitter account retweeted one of the other 74 profiles within an hour. He discovered that the Kremlin's network of Twitter accounts work together to retweet and drive up traffic. This practice is sometimes called "astroturfing" - when the owner of several accounts uses the profiles they control to retweet content and amplify reach.
"It's a coordinated retweet network," Mr Graham says.
"If these accounts weren't retweeting stuff at the same time, the network would just be a bunch of disconnected dots. So what the network shows, very clearly, is that there's a very dense amount of connections to the way these accounts are retweeting.
"They are using this as an engine to drive their preferred narrative onto Twitter, and they're getting away with it," he says.
Coordinated activity, using multiple accounts, is against Twitter's rules.
"You can't artificially amplify conversations through the use of multiple accounts," Twitter's rules state.
But Twitter doesn't treat all accounts equally. Tweets from government and elected officials can be given more leeway when it comes to moderation. The company says on its website that there may be a public interest in seeing tweets that would otherwise violate its rules.
However, the company doesn't treat official accounts differently when it comes to coordinated behaviour - there is no exemption.
