Users are experiencing difficulties sharing links from Signal Messenger on Elon Musk's X platform, as these links appear to be blocked. Reports indicate that attempts to share Signal links result in various error messages, affecting public tweets and direct messages. There has been no official explanation from X regarding this restriction. Journalist Matt Binder noted that links to Signal have seemingly vanished from X, with users reporting similar issues. Error messages encountered range from generic notices to alerts labeling posts as harmful content or spam. While links already posted may carry warnings, they can still be accessed; however, links associated with Signal handles or the main website are currently inaccessible. Elon Musk previously endorsed Signal Messenger as a trustworthy alternative to WhatsApp, but the current blockage suggests a shift in his stance on secure messaging.
