Twitter owner and CEO Elon Musk says he will abide by the results of a Twitter poll asking users whether he should step down as head of the social media company.
Mr Musk launched the poll after posting an apology for announcing "major policy changes" to the platform without consulting the platform's user base, adding that it "won't happen again".
It capped off another tumultuous week for his stewardship of Twitter, which included the suspension and subsequent reinstatement of accounts belonging to journalists who had reported on the company, as well as a decision to ban users from linking to Facebook, Mastodon and other rivals.
That decision generated a wave of criticism, including from past defenders of Mr Musk, and a former Twitter chief executive.
Prolific tweeter finds it's tough at the top
Mr Musk, a long-time user of the platform, paid US$44 billion (about $65.6 billion) for Twitter in October after dropping a court bid to get out of the purchase.
His time running the company has been marked by a string of controversies as he attempts to boost its revenue, as well as settle on an approach to content moderation that balances his professed commitment to free speech with the concerns of advertisers.
His freewheeling decision-making style has seen him publicly announce then quickly reverse major decisions, including changes to Twitter's verification system as well as the reinstatement of users previously banned for hate speech.
Twitter staff have also been on the receiving end of mass lay-offs enacted with seemingly little forethought, with some staff reportedly having to be rehired just days after being shown the door.
The upheaval has at times left Mr Musk appearing despondent. After the poll was published, he told one user who offered to "run Twitter for a bit" that "you must like pain a lot".
Musk has previously said he will step down
Mr Musk's poll is set to close at about 9:20pm AEST, although the billionaire has not set a time line as to when he might step down if the results say he should.
Last month he told a court in Delaware he did not intend to stay on as chief of the company, reportedly testifying that he expected "to reduce my time at Twitter and find somebody else to run Twitter over time".
However, in a reply to another user posted shortly after the poll, Mr Musk said no-one "who can actually keep Twitter alive" wanted the job, and "there is no successor".
