@Twitter Support:
Twitter will remove accounts created to “promote other social platforms” and content with links or usernames to Facebook, Mastodon and others— We noticed 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.
