Twitteron Friday banned ads that deny the reality of climate change.
Twitter's announcement on Earth Day came as it tries to fend off an unwanted takeover bid by billionaire Elon Musk, who has said he thinks people should be able to say pretty much whatever they want on the platform.
"Misleading advertisements onTwitterthat contradict the scientific consensus on climate change are prohibited, in line with ourinappropriate content policy,"Twitterglobal sustainability manager Casey Junod said in a blog post.
"We believe that climate denialism shouldn’t be monetized onTwitter, and those misrepresentative ads shouldn’t detract from important conversations about the climate crisis."
Twitterlast year introduced a Topic feature to help users find conversations about climate change and rolled out hubs of "credible, authoritative" information on an array of high-profile topics including the science backing climate change.
"We recognize that misleading information about climate change can undermine efforts to protect the planet," Junod said.
"Now more than ever, meaningful climate action, from all of us, is critical."
As tempting as access to Musk's wealth may be,Twitteris not eager to be ruled by a billionaire known for shooting from the hip with little regard for the consequences.
The global one-to-many messaging platform is moving to prevent Musk from getting his hands on all ofTwitter's outstanding shares, signalling that worries about where he would lead the company to outweigh the proffered payoff.
Earlier this month Musk, the world's richest person and a controversial and frequent user ofTwitterhimself, made an unsolicited bid of $43 billion for the social media network, citing better freedom of speech as a motivation.
Musk advocates a hands-off approach to policing content, a thorny matter, particularly in high-profile cases such as that of former US President Donald Trump, who was banned after the assault on the Capitol by his supporters as they sought to overturn the US election result last year.
But the polarizing Tesla CEO's campaign has also sparked concern among technology and free-speech experts who point to Musk's unpredictable statements and history of bullying critics, which contradict his stated aims.
Twitter's board opted to employ a "poison pill" defence, under which any acquisition of over 15 per cent of the firm's stock without its OK would trigger a plan to flood the market with shares and thus make a buyout much harder.
