Whether spreading conspiracy theories or organizing riots, the messaging app Telegram has become a focal point for online extremist activity. Launched in 2013, the service is one of the most downloaded apps in the world. Its private chat setup makes Telegram a free space for open discussion in authoritarian regimes. But its relatively lax approach to content moderation means it is now a prime target for governments trying to stop criminal activity and the spread of misinformation that could destabilize societies. On August 24, French authorities arrested CEO Pavel Durov, accusing him of failing to take steps to prevent Telegram from being used for crimes, including the dissemination of child sexual abuse material. The company issued a statement saying it complies with European law.

What is Telegram?

It is a text-based chat service that looks and feels a bit like WhatsApp but with additional features similar to X or Facebook. Telegram chat is a simple everyday communication tool used by hundreds of millions of people around the world.

Users can also post stories, create discussion groups or set up so-called channels. A channel can eventually attract millions of subscribers and become an influential destination for news and information.

New users must agree not to spam or scam users, promote violence or post illegal pornography. But in practice, it conducts less content moderation than large U.S. social media networks. Its moderators routinely remove content that explicitly calls for violence.

How private is Telegram?

The extent of Telegram's encryption remains unclear. While rivals WhatsApp and Signal use end-to-end encryption by default, which is considered one of the best ways to protect users' messages, Telegram does not.

Instead, the site only offers end-to-end encryption to users who initiate “secret chats,” making messages unreadable to both Telegram and any potential snoopers. Telegram also relies on its own proprietary encryption protocol, which means that, unlike Signal, security experts cannot test and verify that the company does what it claims.

Why is Telegram a powerful tool for extremists?

Content on Telegram is not pushed to users based on their engagement history like on other platforms like X, TikTok, or Facebook.

But hate speech and misinformation can still spread on Telegram. One reason is that users can cross-post their content from one channel to others. For example, users who follow a channel of supporters of U.S. presidential candidate Donald Trump could become targets of conspiracy theorists who post links to their own channels with more offensive political content.

If users click on these links, they can find themselves interacting with more radical users, sharing more extreme narratives.

Why are governments so concerned about Telegram?

It has proven difficult to track down extremists who join the platform and send false or inflammatory messages directly to individuals or in chat rooms and channels.

Law enforcement agencies have more leverage to convince Facebook and WhatsApp owner Meta Platforms Inc. to help them identify users engaging in illegal activity because it is a publicly traded company based in the U.S. They have proven largely powerless when it comes to Dubai-based Telegram.

Pro-Russian accounts are particularly active on Telegram, spreading disinformation aimed at undermining support for Ukraine. Russian intelligence operatives use it to recruit petty criminals to carry out sabotage operations in European capitals. Many Ukrainians also use Telegram, including President Volodymyr Zelensky.

Durov's arrest was a memorable moment for the site, which for years resisted calls to remove vile content. French officials questioned the executive as part of a case launched by the cybercrime unit of the Paris prosecutor's office. The government said the investigation focused on a range of allegations, including that Durov refused to help authorities conduct a legal wiretap on a suspect and that Telegram facilitated the sale of child sexual abuse material.

After Durov's arrest, Telegram called the charges "ridiculous" in a statement.

What role did Telegram play in the UK riots?

Telegram was used to incite and coordinate anti-immigrant riots in the UK in early August.

A study by the Institute for Strategic Dialogue, a London-based counter-extremism think tank, showed that after the murder of three girls in Southport, northern England on July 29, extremists used Telegram channels to incite hatred against Muslims, spread the locations and targets of actions, and circulate practical advice for would-be rioters.

The study examined 16 prominent Telegram channels and groups "that actively posted, hosted and forwarded anti-Muslim and anti-immigrant content related to the riots." Six channels created in direct response to the riots were removed from the platform on August 5 and 6, the study found.

When asked about the app’s role in the UK unrest, a Telegram spokesperson said its moderators “are actively monitoring the situation and removing channels and posts that contain calls for violence.” The spokesperson said the monitoring includes direct supervision of the public parts of the platform, the use of artificial intelligence tools and user reporting.

British Prime Minister Keir Starmer has pledged to crack down on social media platforms that fuel the riots.

What is the origin of Telegram?

Telegram was created by Russian entrepreneur Durov and his brother, programmer and mathematician Nikolai. They made their fortune in 2006 by creating the Russian social network VKontakte. Pavel fled the country and sold his shares in VKontakte. Around that time, the idea for Telegram was born, and Nikolai developed the platform's data transmission system.

Sometimes referred to as Russia's Mark Zuckerberg, Pavel continues to live in self-imposed exile. He frequently makes headlines for his wealth, with a net worth of more than $10 billion.

The platform is inextricably linked to cryptocurrency and launched its own initial coin offering in 2018, called Telegram Open Network.

How does Telegram make money?

In 2020, Pavel Durov announced plans to monetize the platform, which had previously had no revenue since its creation. A subscription version, Telegram Premium, was launched in 2022. Users can pay to get an enhanced Telegram experience, including faster downloads and greater file upload speeds.

It also introduced a rewards system where content creators can keep 50% of the advertising revenue on their channels. However, most of the platform’s funding still comes from the founders themselves.
