The app has spawned numerous viral trends, Internet celebrities, and music trends around the world. On 19 July 2023, TikTok Music was expanded for select users in Australia, Mexico and Singapore. However, a few days later, users on Twitter discovered that the software uses code from the open-source OBS Studio. Accounts of users that are of age, have at least 100,000 followers and agree to the terms can activate a “Tip” button on their profile, which allows followers to tip any amount, starting from $1. The app expanded its parental controls feature called “Family Pairing” in September 2020 to provide parents and guardians with educational resources to understand what children on TikTok are exposed to. TikTok announced a “family safety mode” in February 2020 for parents to be able to control their children’s presence on the app.

Restrictions and bans

In August 2024, the NCRI released a subsequent report based on user journey data from 24 accounts that they created across TikTok, Instagram, and YouTube. After increased scrutiny, TikTok said it is granting some outside experts access to the platform’s anonymized data sets and protocols, including filters, keywords, criteria for heating, and source code.

App Privacy

The differences between Douyin and TikTok have led some US politicians and commentators to accuse the company or the Chinese government of malicious intent. Out of TikTok’s top 100 male creators, a 2022 analysis reported 67% were white, with 54% having near-perfect facial symmetry. The average user, daily, was spending 1 hour and 25 minutes on the app and opening TikTok 17 times.

The consumption of alcohol, full or partial nudity, LGBT, and intersex contents were restricted even in places where they are legal. A more specific list banned criticisms against world leaders, including past and present ones from Russia, the United States, Japan, North and South Korea, India, Indonesia, and Turkey. However, some employees have abused it to promote their own accounts or those of their spouses, while others have felt that their guidelines leave too much room for discretion.

In June 2021, US President Joe Biden signed an executive order revoking the Trump administration ban on TikTok, and instead ordered the Secretary of Commerce to investigate the app to determine if it poses a threat to US national security. In January 2020, the United States Army and Navy banned TikTok on government devices after the Defense Department labeled it a security risk. An analysis estimated that Meta, the parent company of Facebook and Instagram, could gain between $2.46 billion and $3.38 billion in advertising revenue if TikTok were banned.
Duets, a feature that allows users to add their own video to an existing video with the original content’s audio, have sparked many of these trends. In December 2021, TikTok started beta-testing Live Studio, a streaming software that would let users broadcast applications open on their computers, including games. Users can choose whether any other user, or only their “friends”, may interact with them through the app via comments, messages, or “react” or “duet” videos. The app’s “react” feature allows users to film their reaction to a specific video, over which it is placed in a small window that is movable around the screen.

The founder of ByteDance, Zhang Yiming, stated that “China is home to only one-fifth of Internet users globally. If we don’t expand on a global scale, we are bound to lose to peers eyeing the four-fifths. So, going global is a must.”
In May 2023, The Wall Street Journal reported that former employees complained about TikTok tracking users who had viewed LGBT-related content.

TikTok partnered with the National Association of Secretaries of State to give accurate local information to users. TikTok removed some of these videos and has generally added links to accurate COVID-19 information on videos with tags related to the pandemic. Although they were removed by TikTok after the report, mixing audio remains an effective way to evade content moderation on many platforms. In September 2024, Sky News reported that clips of Adolf Hitler’s speeches with added music were attracting high levels of engagement on TikTok.

Douyin

On 22 January 2021, the Italian Data Protection Authority demanded that TikTok temporarily suspend Italian users whose age could not be established.

In January 2020, left-leaning media watchdog Media Matters for America said that TikTok hosted misinformation related to the COVID-19 pandemic despite a recent policy against misinformation.
