Twitter on Sunday said that it will remove accounts created solely for the purpose of promoting other social platforms and content that contains links or usernames.
The move would impact content from social media platforms like Meta Platforms' Facebook and Instagram, along with Mastodon, Truth Social, Tribel, Nostr and Post while allowing cross-content posting, Twitter support said in a tweet.
Short video-platform TikTok, owned by China's ByteDance Ltd, was not included in the list.
Last week, Twitter disbanded its Trust and Safety Council, a volunteer group formed in 2016 to advise the social media platform on site decisions.
The policy change follows other chaotic actions at Twitter since Elon Musk, who is also the CEO of Tesla, bought the social network. He fired top management and laid off about half of its workforce, while seesawing on how much to charge for Twitter's subscription service Twitter Blue.
Musk also suspended the accounts of several journalists over a controversy on publishing public data about the billionaire's plane.
Musk reinstated the accounts after criticism from government officials, advocacy groups and journalism organizations from several parts of the globe on Friday, with some saying the microblogging platform was jeopardizing press freedom.
