Twitter said Thursday it had removed more than 170,000 state-linked accounts used by China, Russia and Turkey.
The US-based social media company said these accounts consisted of a network of echo chambers, used to push propaganda, spread misinformation or attack critics of the government.
The biggest network of these accounts was linked to China, with 23,750 that were further boosted by 150,000 “amplifier” accounts.

The Turkish and Russian networks were much smaller, with 7,340 and 1,152 accounts respectively.
The accounts and their content have been removed from Twitter, but will be archived on a database for research.
Last year, Twitter had also detected a Chinese network during pro-democracy protests in Hong Kong. The social media giant said the same systems were used to detect the most recent network, although it was not as influential. Twitter’s analysis said this network was involved in a “range of coordinated and manipulative activities.
