Social media app TikTok has apologised to teenager Feroza Aziz for suspending her account after she posted a viral clip, criticising China's treatment of Uighur Muslims.
TikTok says it has now lifted the ban on the 17-year-old's account, which was suspended shortly after she posted the series of videos, which have been viewed more than 1.6 million times.
In a public apology, the Chinese-owned social media app said the teenager's account was suspended because it was linked to another account - where Ms Aziz had posted a video that included a picture of Osama Bin Laden - which is against the platform's rules -not because it criticised China.
Ms Aziz had used the same phone to create the second account, but TikTok says when a user is banned it also prevents another account being set up using the same device.
Ms Aziz took to Twitter to say she doesn't believe this explanation.
It was on the second account, set up on the same device, that Ms Aziz posted the now-viral video.
The post - disguised as a makeup tutorial - shows Ms Aziz using an eyelash curler and abruptly stopping, encouraging viewers to "search up what is happening in China".
She says the ban will not discourage her from speaking about this issue.
"I'm not scared of TikTok, even after the suspension," Ms Aziz told the BBC.
"I won't be scared of TikTok."
The viral video was also removed from TikTok for almost an hour.
The app's US head of safety Eric Han admitted the post should not have been removed, apologising for the 'human error' that caused the suspension.
"It's important to clarify that nothing in our community guidelines precludes content such as this video, and it should not have been removed," he said.
The video has now been restored alongside Ms Aziz's account.
Human rights groups say more than one million Uighurs and other mostly Muslim minorities are being held in concentration camps in the Xingjiang region.
China says the camps are for vocational re-training, but leaked Chinese government documents reveal the mass detention is for forced indoctrination.
TikTok has come under scrutiny for its lack of transparency in recent months
The Beijing-based company that owns TikTok - ByteDance - is being investigated by the US Committee of Foreign Investment in the United States, following its purchase of music-based social network Musical.ly in 2017.
The social media app is not available in China but the app has been downloaded 1.5 billion times globally.
