Elon Musk has announced a general amnesty for suspended Twitter accounts in a move that brought a warning that “superspreaders of hate” will return to the social media platform.

Twitter’s new owner said an amnesty for blocked users would begin next week after a majority of votes in a poll on his account backed the move. Accounts suspended on Twitter include Donald Trump’s former adviser Steve Bannon, rightwing UK commentator Katie Hopkins and David Duke, the former Ku Klux Klan grand wizard.

Musk had launched a poll on Wednesday asking if a general amnesty should be offered to accounts provided they have not “broken the law or engaged in egregious spam”. Musk did not specify which laws he meant. More than 3.1m votes were recorded by the poll, with 72% in favour of an amnesty
