While many people were watching the World Cup on Sunday, the company introduced a new policy that banned free promotion of competing social media websites. Donald Trump's Truth Social will be removed from accounts that promote content on those platforms. As a result of the policy, users can no longer use their bio to link to their other social media profiles. The company is limiting the use of third-party aggregations. Users who try to circumvent the new policy using technical means will be found in violation.

We recognize that many of our users are active on other social media platforms. However, we will no longer allow free promotion of certain social media platforms on Twitter.

Two exceptions have been carved out by the company. Some social media platforms allow users to post content to Twitter from their platforms, and we are aware of that. Any type of cross-posting to our platform is not in violation of this policy. There will be paid promotion for any of the platforms on the banned list.

If the account is their first offense or an isolated incident, it may be locked down. The offending tweet will be deleted. Any subsequent offenses will result in permanent suspension. The offending links will be temporarily locked from the accounts. Multiple violations may result in permanent suspension, as was the case last time.

The policy was put in place after another messy week at the micro-blogging site. NBC's Ben Collins and CNN's Donnie O' Sullivan were among a group of journalists who couldn't access their accounts on December 15. Most of the accounts talked about Jack Sweeney or his account for breaking the policy against public location sharing. The Washington Post journalist's account was suspended on Saturday after she asked Musk to comment on an upcoming story. At that time, there wasn't a policy against linking to competing platforms, nor was it mentioned in the new rule.
