"Elon Musk’s social media platform, X, is currently banning links to “Signal.me,” a URL used by the encrypted messaging service Signal. The “Signal.me” domain is specifically used by the service so that users can send out a quick link to directly contact them through the messaging app.
X, formerly Twitter, is blocking users from posting a “Signal.me” link through DM, public post, or even in their profile page. When trying to post a Signal link, users receive a variety of different “message failed” prompts depending on what version of the X platform they use (i.e. X for web, X for iPhone, etc.)"
EDIT: This appears to actually be a mitigation for this attack:
