Twitter has suspended the accounts of several members of the American alt-right movement, including the leader of a white nationalist think tank.
The social network has not given an explanation for its actions.
But they come the same week it announced new ways for users to complain about hateful content.
Some alt-right figures have suggested a switch to Gab, an alternative micro-blogging service that promises “free speech for everyone”.
But other have their doubts.
“Gab just seems like a pointless echo chamber, there are enough alt-right blogs and forums,” wrote one supporter of the movement in a discussion thread about the Twitter suspensions.
“The benefits of Twitter are interacting with normies, influencing discussion and getting alt-right memes trending.”
Members of the alt-right movement differ on many points, but are generally outspoken in their attacks on multiculturalism, globalisation and immigration.
Their targets include political correctness and feminism, and they have typically characterised themselves as being anti-establishment.
The election of Donald Trump – a presidential candidate supported by much of the alt-right – could change that.
He has appointed Steve Bannon as his chief strategist. Mr Bannon was formerly executive chairman of Breitbart News, a news site that specialises in coverage of the alt-right, but does not identify itself as part of it.
That has led some to speculate about whether certain alt-right views could soon become official US policy.
