Twitter permanently banned some users, such as former President Donald Trump, from accessing their accounts. Now, Elon Musk says he might let banned users back on the platform, per The Wall Street Journal.

Twitter has rules that prohibit certain behaviors or speech from being used on the platform. If a user posts hate speech, harassment, terrorism or glorification of violence, the user’s account could be suspended or permanently closed.

“Our rules are to ensure all people can participate in the public conversation freely and safely,” the company says on its website.

Hate speech on Twitter has increased since Elon Musk took over, study finds

In January 2021, Trump was banned from Twitter for violating the platform’s Glorification of Violence policy for his posts following the Jan. 6 attack on the U.S. Capitol. Twitter banned Trump’s account “due to the risk of further incitement of violence,” Twitter wrote in a press release.

Trump is one of many permanently banned Twitter users, although many banned users are connected to him. The Wall Street Journal released a list of people whose accounts were permanently suspended.

What is Elon Musk’s plan for banned accounts?

On Tuesday, Musk tweeted that Twitter “will not allow anyone who was de-platformed for violating Twitter rules back on the platform until we have a clear process for doing so, which will take at least a few more weeks.”

Musk claimed on Twitter that he is developing a plan that will allow Twitter to “combat hate & harassment & enforce its election integrity policies.” The new Twitter owner said that he met with “civil society leaders,” such as the presidents of the NAACP and Color for Change, to gather insights on what Twitter’s next steps will be.

Opinion: Elon Musk’s battle to defend free speech

Musk, a self-declared “free speech abolitionist,” previously criticized Twitter for banning Trump from his account, which he called “a morally bad decision” and “foolish to the extreme,” per Business Insider.

Musk has repeatedly publicly criticized Twitter’s policies on hate speech, violence and harassment — the ones that got so many users banned from the platform, per NPR.

In April, Musk tweeted, “I hope even my worst critics remain on Twitter, because that is what free speech means.”

When Musk first acquired the social media platform last month, he shared his reasons for buying the platform. In a multi-paragraph message, Musk tweeted that he did not obtain the platform for the money but rather “to help humanity, whom I love.”

In May, before Musk bought the platform, he said, “Free speech is the bedrock of a functioning democracy, and Twitter is the digital town square where matters vital to the future of humanity are debated.” He added, “I also want to make Twitter better than ever by enhancing the product with new features, making the algorithms open source to increase trust, defeating the spam bots, and authenticating all humans.”

Since acquiring Twitter, Musk has already made some changes. He fired the CEO and CFO after the deal closed, The Wall Street Journal reports.

So far, Musk has not publicly revealed an official plan for how he will run the platform. It is mostly left to speculation based on comments he has made.
