- Twitter removed more than 100 accounts using the hashtag #IStandWithPutin, NBC reported.
- The accounts were flagged for "coordinated inauthentic behavior" in violation of the company's "manipulation and spam policy."
- Many of the tweets mysteriously went viral despite coming from accounts with few followers and stock imagery profile pictures.
Twitter banned more than 100 accounts using the hashtag #IStandWithPutin in violation of the social media platform's "manipulation and spam policy," NBC reported.
According to NBC, Twitter removed the accounts for participating in "coordinated inauthentic behavior," after several of the tweets went mysteriously viral despite coming from accounts with relatively few followers and stock imagery for profile pictures.
Twitter did not immediately respond to Insider's request for comment, but the company told NBC in a statement on Friday it's investigating the accounts using the hashtag.
The tweets were first identified by Owen Jones, an assistant professor of Middle East studies and digital humanities at Hamad Bin Khalifa University in Qatar, who told NBC he noticed "lots of accounts demonstrating inauthentic activity and astroturfing."
"They're not bots. They're a lot harder to check than that," Jones told NBC. "Imagine a call center setup. Think of the amount of damage you can do."
The Twitter ban is part of a larger effort among tech companies to crack down on the spread of misinformation in the wake of Russia's invasion of Ukraine.
Last week, Twitter began adding cautionary labels to tweets with content from Russian state-funded media channels, while platforms like Facebook and YouTube pulled all ads in the country and blocked Russian advertisements globally.
"Due to the difficulties of operating in Russia at this time, ads targeting people in Russia will be paused, and advertisers within Russia will no longer be able to create or run ads anywhere in the world, including within Russia," Facebook said on Friday.
On Thursday, reports emerged that Twitter had been blocked or limited in Russia, along with fellow Western media sites like Facebook, according to state-owned media.
