Google announced Thursday that it deleted 58 accounts with ties to Iran on its video platform YouTube and its other sites, the latest sign that foreign agents from around the world increasingly seek to spread disinformation on a broad array of popular websites.
The new removals targeted 39 channels on YouTube, which had more than 13,000 views in the United States, as well as 13 accounts on the social networking site Google Plus and six accounts on Blogger, its blogging platform, the company said. Kent Walker, Google's senior vice president of global affairs, said in a blog post that each of the accounts had ties to the Islamic Republic of Iran Broadcasting, or IRIB, which is tied to Iran's ayatollah, and that they "disguised their connection to this effort."
Google's announcement comes days after Facebook Inc. suspended hundreds of accounts on its site and photo-sharing app Instagram that originated in Iran as well as Russia, and Twitter Inc. made a similar move. At the time, YouTube confirmed it had removed one account, called Liberty Front Press, which appeared to have connections to Iranian state media.
Google, a division of Alphabet Inc., also revealed Thursday that it took down 42 additional channels on YouTube that had ties to the Russian government's online troll army, called the Internet Research Agency, since the company testified to Congress in November.
Facebook acted on a tip from the cybersecurity firm FireEye, which later shared its findings with Google and Twitter. In response, Google briefed law enforcement officials and congressional investigators about its findings Thursday, the company said.
The revelations of further coordinated inauthentic activity online are likely to grab lawmakers’ attention. The Senate Intelligence Committee plans to question top executives from Facebook, Google and Twitter next month on their efforts to protect their platforms from disinformation and other digital ills.
On Thursday, the Republican chairman of the panel, Sen. Richard Burr, said he had rejected an offer by Google to send Walker to testify. "I told them I wasn't accepting the senior vice president," Burr said.
