Twitter abruptly bans all links to Instagram, Mastodon and other competitors

Twitter no longer allows users to promote their presence on certain social platforms, including Facebook, Instagram, Mastodon, Truth Social, Tribel, Nostr, and Post. In a message describing these changesTwitter says it will take action against users who violate this policy “at both the Tweet and account levels.”

This means users will no longer be able to include links to their profiles on other social networks (or even include their username without a URL) in their Twitter biography, nor will they be able to link to their posts on banned platforms, unless it’s a cross-post . Twitter also says it may suspend accounts “primarily used for promoting content on another social platform,” and will no longer allow users to link to third-party link aggregators, such as Linktree or Despite this, Twitter is still fine with the paid promotion of these banned platforms:

We recognize that certain social media platforms provide alternative experiences to Twitter and allow users to post content to Twitter from those platforms. In general, any form of cross-posting on our platform does not violate this policy, even from the prohibited sites listed above. In addition, we allow paid advertising/promotions for any of the prohibited social media platforms.

Twitter says it will delete any tweets containing policy violations, and may temporarily suspend users with links to banned social platforms in their profiles. It will also take action against users who try to circumvent this policy by cloaking URLs to other platforms or spelling “dot” for social media platforms that use ‘.’ in the names to avoid creating URLs, or sharing screenshots of your handle on a banned social media platform.

Twitter already banned links to Mastodon and blocks users from posting them at the platform level. Attempting to tweet a link to different Mastodon servers or the site itself results in an error message stating, “We are unable to complete this request because this link has been identified by Twitter or our partners as potentially malicious.” It’s unclear whether Twitter will eventually disable links from the banned platforms in a similar fashion, but at the time of writing, it appears that users will still be able to post links from these networks. Twitter did not immediately respond The edgerequest for comment.
