Yes—independent researchers have documented pro‑ISIS material and supporter networks on TikTok. The evidence shows specific accounts reposting Islamic State media, disguising extremist messages in TikTok-style content and directing audiences elsewhere. It does not establish how widespread this activity is across TikTok, that TikTok’s recommendation system intentionally promotes terrorism, or that viewing a post causes radicalization.
What “ISIS” means in this reporting
This article uses “ISIS” (also called the Islamic State or IS) for the terrorist organization and its supporters. The findings concern a small number of observed accounts and posts; they are not claims about Muslims generally or about TikTok’s entire user base.
What the evidence actually documents
| Source and date | What was examined | What it reported | What it cannot show |
|---|---|---|---|
| *Social Media + Society* study, 2026 | Researchers’ analysis of TikTok conventions used by ISIS and al‑Qaeda supporters | Five techniques for disguising or delaying extremist meaning: audio camouflage, meme infiltration, blurred intent, emoji codes and bait-and-switch | How common each technique is, or its effect on viewers |
| George Washington University Program on Extremism paper, 2026 | 25 pro‑ISIS accounts over a two-week observation window | Predominantly Arabic and English posts (two accounts also used German), with masking, coded communication, fragmented distribution and movement to other platforms | A representative sample of TikTok or a measure of total ISIS activity |
| Institute for Strategic Dialogue investigation, June 2023 | 20-account support network; more than 100 videos reviewed | More than one million collective views; five accounts were removed during the observation period; operators appeared to use dormant accounts and links to Telegram or an external site | Current availability, current view totals or activity beyond that investigation |
| Counter Extremism Project report, April 2025 | One pro‑ISIS account observed by CEP | CEP reported one post exceeding 10,000 views in ten days and another exceeding 17,000 in nine days; the account was still online on April 28, 2025 | Whether the material remains online now, or whether viewers acted on it |
How supporters adapt propaganda to TikTok
The 2026 academic study describes tactics as a typology, not a prevalence ranking. In broad terms, the researchers observed:
Audio and visual camouflage
Supporters can alter recorded audio, metadata or imagery so that extremist material is less immediately recognizable. “Blurred intent” refers to obscuring sensitive visuals rather than presenting an obvious propaganda clip.

Meme and pop-culture framing
Extremist references may be embedded in familiar memes, sounds or visual styles. The researchers call this “meme infiltration,” describing a form of everyday extremism embedded in TikTok’s vernacular practices, aesthetics and pop-culture references.
Coded communication
Emoji, symbols, altered names and indirect language can help supporters signal to one another while making automated or casual review harder. The studies describe these as observed communication practices, not a universal code used by every account.

Delayed or fragmented messaging
“Bait-and-switch” delays the extremist message, while fragmentation spreads material across accounts or platforms. Cross-platform links and migration can make a network harder to understand from any single post.
Does TikTok remove ISIS propaganda?
TikTok says its rules prohibit violent and hateful organizations and individuals, including their promotion or material support. In a November 19, 2025 newsroom statement, the company said it removes violating content, terminates accounts, reports appropriate cases to law enforcement and investigates networks that use coded language, rebrand accounts or direct users off-platform. TikTok’s statement is available at its newsroom page.

The company said this was just under 2% of all violative content removed in that period, with 98.9% removed before users reported it and 94% removed within 24 hours. Those are platform-wide, company-reported figures—not a count of ISIS posts and not an independent audit.
Independent monitoring nevertheless found examples that remained available during particular observation periods. ISD reported five removals among the 20 accounts it watched in 2023, while CEP said the account in its April 2025 report was still online on April 28. These observations document enforcement gaps at those times; they do not establish the platform’s current total of extremist content.
What the studies do—and do not—say about radicalization
The reviewed work documents presence, tactics and possible pathways for persistence. It does not demonstrate that seeing an ISIS post causes someone to become radicalized, join the organization or commit violence. Nor does it prove that TikTok’s recommendation system deliberately promotes terrorism. Researchers raise concerns about recommendation loops, participatory features and uneven moderation, but those concerns are not the same as a measured platform-wide causal effect.
Why the findings matter
- Short-form presentation lowers obvious warning signs. Repurposed sounds, memes and edited visuals can make a post look like ordinary entertainment until its context is understood.
- Networks can outlast individual takedowns. Dormant or replacement accounts, fragmented uploads and off-platform destinations can preserve access after one account disappears.
- View counts need context. The 2023 ISD total and the 2025 CEP counts are observations attached to named accounts and dates, not estimates of a nationwide or worldwide audience.
- Moderation metrics answer a different question. TikTok’s millions of removals describe enforcement across its violent-and-hateful-organizations policy, not success against ISIS specifically.
How to respond to suspected extremist content
- Do not repost, download or quote the material. Sharing can increase its reach and preserve harmful instructions or propaganda.
- Use TikTok’s in-app reporting option for violent or hateful organizations and related content, following the current prompts shown in your region.
- If there is an immediate threat or specific plan to harm people, contact local emergency services or law enforcement. Preserve only the information authorities need; do not circulate the post or its links.
- For research or journalism, record the date, account URL and a non-graphic description in a secure channel, while avoiding publication of attack guidance, coded search terms or identifying details that could amplify the network.
Bottom line
ISIS supporters have used TikTok to publish and circulate propaganda, and multiple investigations found techniques designed to blend extremist messaging into the platform’s culture or move audiences to other services. The evidence is real but bounded: small, dated samples show presence and moderation challenges, not platform-wide prevalence, intentional algorithmic promotion or proven radicalization.
