"There is a small possibility that appearances are deceiving," the billionaire wrote Sunday morning in a tweet to his 123 million subscribers, deleted in the afternoon.

His post referred to the assault on Paul Pelosi, and linked to an article from the conservative Santa Monica Observer site spreading unverified information about the attack.

This medium has already published conspiracy theories and false information in the past, according to the daily Los Angeles Times.

Paul Pelosi was attacked at his home on Friday by a man with a hammer, who was actually looking for Nancy Pelosi.

He suffered in particular from a fractured skull and had to be hospitalized.

Elon Musk was reacting to a tweet from former Democratic presidential candidate Hillary Clinton castigating conspiracy theories peddled by the Republican Party.

"The Republican Party and its spokespersons now regularly propagate hate speech and completely crazy conspiracy theories," denounced the former American secretary of state.

"It's shocking but not surprising, and violence is the result."

US President Joe Biden also denounced this weekend the aggression of Mr. Pelosi, linking it to the consequences of disinformation, ten days before the mid-term elections.

Deluge of insults

Elon Musk's tweet drew a lot of comments and criticism on the social network.

"Clinton: conspiracy theories are responsible for people's deaths and we shouldn't give them visibility. Twitter owner: but have you heard of this conspiracy theory?", summarized Seth Masket, professor of science policies at the University of Denver, which flagged Elon Musk's tweet as inappropriate to the social network.

“The Elon troll should alert Twitter chief Elon to the withdrawal (of this tweet), commented the former UN special rapporteur for freedom of expression David Kaye, ironically on the different caps of the billionaire.

Asked by AFP, Twitter did not respond immediately.

The whimsical boss of Tesla and SpaceX, who sets himself up as a defender of freedom of expression, has repeatedly affirmed that he wants to make Twitter a kind of digital agora, where all opinions are free to express themselves.

He defended a too strict moderation of the contents, however concentrating the majority of his attacks against the supposed censorship of the voices of the right and far-right.

However, seeking to reassure his advertisers, Elon Musk promised after his acquisition of Twitter that the social network would not become "hellish" and that he would provide it with a "content moderation council".

Barely a few days after its takeover, the blue bird network is already the subject of coordinated attacks from "trolls" dumping hateful content to test its moderation policy, according to a company official.

“Over the past 48 hours, we have seen a small number of accounts post a deluge of tweets containing slurs and other insulting language,” said Yoel Roth, in charge of the integrity of the platform, on Saturday.

“To give you an idea of ​​the scale: more than 50,000 tweets mentioning a particular insult came from only 300 accounts,” he added, specifying that the vast majority were fake accounts.

Mr Roth reiterated that 'hate speech had no place' on Twitter as its moderation policy had not 'changed', and that the company was taking steps to 'stop any organized effort to make people believe the opposite".
