about 14 million people were affected by a bug that, for a nine-day span between May 18 and 27, caused profile posts to be set as public by default, allowing any Tom, Dick or Harriet to view the material.

“We recently found a bug that automatically suggested posting publicly when some people were creating their Facebook posts. We have fixed this issue and starting today we are letting everyone affected know and asking them to review any posts they made during that time,” Facebook chief privacy officer Erin Egan said in a statement to The Register.
