US President Donald Trump put a label on Facebook on Tuesday after he said the mail vote could lead to a “corrupt election,” foreign media reported. But the tag did not attempt to verify the authenticity of the post. Instead, it guides users to a government website to learn more about how to vote.

the response is part of Facebook’s new policy, announced last month by CEO Mark Zuckerberg, to label posts about the November election. In recent days, Facebook has put the same tag under a series of posts by trump and presidential candidate Joe Biden.

this new approach has been criticized by some industry observers, who worry that labels can be confusing and may even be seen as tacit approval of the president’s controversial posts.

Rick Hasen, a professor of law and political science at the University of California, Irvine, wrote on Twitter: “this warning doesn’t seem to work – it may even make Facebook seem to support Trump’s remarks and provide access to more information.”

according to Andy stone, a Facebook spokesman, the tagging feature has been launched in the past few days. Earlier, employees and civil rights leaders have criticized Facebook for not acting on Trump’s earlier inflammatory posts.

Zuckerberg said last month that Facebook was focused on preventing new forms of repression by potential voters, but pointed out that it was difficult to identify such repression on a large scale. He said the company would add links to voting information on posts discussing the election, including those from politicians. “It’s not about judging whether the post itself is accurate, but we want people to have authoritative information anyway,” he said

it is understood that Trump’s post on Tuesday was considered wrong. Because there are safeguards to protect the integrity of postal ballots, there is no widespread fraud in American elections. During the flu pandemic, Republican officials and across the United States have expanded the scope of postal voting. Experts predict that the mail vote will reach a record level in November this year.
