The first revenue-based fine of its kind in Russia, the court decision is the latest in Moscow's pile of fines on internet platforms accused of defying the country's regulations.
A Russian court slapped Google with a nearly $100 million fine and also fined Facebook’s parent company Meta $27 million over their failure to delete content banned by local law.
The Tagansky District Court on Friday ruled that Google repeatedly neglected to remove the banned content, and ordered the company to pay an administrative fine of about $98.4 million (7.2 billion rubles).
Google said it would study the court documents before deciding on its next steps.
Later on Friday, the court also slapped a fine of nearly $27.2 million (2 billion rubles) on Meta for failure to remove banned content.
Russian courts had previously imposed smaller fines on Google, Facebook and Twitter this year, and Friday's rulings marked the first time the size of the fine was calculated based on revenue.
At odds with Moscow
Russian state communications watchdog Roskomnadzor said Google and Meta were specifically accused of violating the ban on distributing content that promotes extremist ideology, insults religious beliefs and encourages dangerous behavior by minors, among other things.
The agency said that Facebook and Instagram have failed to remove 2,000 items despite the courts’ requests to do so, while Google has failed to delete 2,600 such items.
It warned that they may face more revenue-based fines for failure to delete the banned content.
Russian authorities have steadily ramped up pressure on social media platforms, accusing them of failing to purge content related to drug abuse, weapons and explosives and extremist views.
Earlier this year, authorities criticised tech companies for not deleting announcements about unsanctioned protests in support of jailed Kremlin critic Alexey Navalny.
Russian authorities also have demanded that foreign tech giants store the personal data of Russian citizens on servers in Russia, threatening them with fines or possible bans if they fail to comply.
Alexander Khinshtein, head of the committee on information policies in the lower house of Russian parliament, said the massive fine should send a clear message to all IT giants.
He added that Russian law envisages other forms of punishment for failure to comply with court orders, including slowing down traffic and complete blocking.
