Marguerite Joseph's granddaughter says Facebook won't let Joseph list her real age.
Gail Marlow says when she tries inputting her grandmother's birth year as 1908, Facebook changes it to 1928. So for the past two years, the Grosse Pointe Shores centenarian has remained 99 - online, anyway.
Joseph is legally blind and can't hear well, but Marlow reads and responds to all her Facebook messages.
Facebook spokesman Andrew Noyes told The Associated Press on Wednesday that it's working to fix a problem limiting used of pre-1910 birthdates.
