The claim is supported by two independently fetched secondary reports: PANews and BlockBeats. Both state that CZ said the number had been deactivated years ago and that the current owner may be a hacker or police impersonator, and both frame this as a warning not to add that contact. PANews explicitly links to https://x.com/cz_binance/status/2041794551757553855 as the original statement, and the Odaily media trace independently identified that same X URL as the upstream source. However, because direct fetching of the X post failed in this run, the primary-source text itself could not be validated directly, which lowers confidence from high to medium.
