A technological crackdown, telegraphed by Mormon leaders, has effectively blocked the pre-eminent whistle-blower of controversial proxy baptisms from accessing the LDS Church’s database that chronicles so-called baptisms for the dead. LDS officials defend the move, saying it helps prevent overzealous Mormons and mischief-makers from violating church policy by submitting the names of prominent Jewish figures, such as Anne Frank and Daniel Pearl, both discovered on the baptism rolls in recent weeks.
