X, formerly known as Twitter, has implemented significant changes to its algorithm and user interaction policies under the leadership of Elon Musk. The updates include the removal of previous rules that restricted user speech, allowing for more open expression. Additionally, the platform has revised its blocking functionality to prevent scammers and trolls from exploiting the system. Previously, scammers could pre-block users and send hidden scam messages, which made it difficult for legitimate users to block and report them. These changes are aimed at enhancing user experience and security.
