Meta & Children's Online SafetyMeta terminology
DOB
date of birth
The self-reported birthday on an account, and the pivot of age enforcement. The source document reports "~2k FB accounts per day... making a DOB change where they explicitly check a box confirming they are <13 before saving (but we don't lock them out/checkpoint them - just throw an error)", and calls that "a major COPPA risk for us to keep them active, as it constitutes explicit knowledge of U13".
