X, the social platform formerly known as Twitter, is seemingly blocking links to Signal, the encrypted messaging platform, according to journalist Matt Binder and other firsthand accounts.

Binder wrote in his Disruptionist newsletter Sunday that links to Signal.me, a domain that offers a way to connect directly to Signal users, are blocked on public posts, direct messages, and profile pages. Error messages—including “Message not sent,” “Something went wrong,” and profiles tagged as “considered malware” or “potentially harmful”—give no direct suggestion of a block. But posts on X, reporting at The Verge, and other sources suggest that Signal.me links are broadly banned.

Signal.me links that were already posted on X prior to the recent change now show a “Warning: this link may be unsafe” interstitial page rather than opening the link directly. Links to Signal handles and the Signal homepage are still functioning on X.

Binder, a former Mashable reporter who was once blocked by X (then Twitter) for reporting on owner Elon Musk and accounts related to his private jet travel, credited the first reports to an X post by security research firm Mysk.
