In another warning sign for investors using the Internet, a bogus posting from someone claiming to be Metro-Goldwyn-Mayer Inc.’s former chairman led the film studio to post a note telling investors to beware. Late Tuesday, visitors to a Yahoo! message board would have seen a note from someone using the name frankgmancuso, advising shareholders to sell MGM stock ahead of a planned stock rights offering. The real Frank G. Mancuso resigned as MGM chairman and chief executive last spring, but he is still a consultant and member of its board. But Mancuso did not post the note. Investors quickly called his office. After consulting with attorneys, MGM posted a message using the name, mgmcorporate, warning investors that Mancuso was not the posting’s source.
