"Checkpointing U13U13Under-13Users below the minimum age of 13 set by Meta's terms of service and by COPPA. "U13" denotes both the age cohort and the underage accounts Meta's own documents discuss detecting, removing, or building products for.Full entry ↗ users on DOB change, -3.4M MAPMAPMonthly Active PeopleCore Meta engagement metric counting distinct people active on a platform in a month. Paired with DAP in internal goal-setting; the MAP/DAP ratio is used as a measure of how frequently a monthly user returns.Full entry ↗/year hit if launched Context 1. Right now, when users attempt to change their birthday in a logged-in state, we do not allow them to change it to under 13. 2. We need to checkpoint the people who attempt to change to under 13 with a photo ID challenge. 3. We currently have very aggressive placement for entry points to DOB changes. 4. We currently do not have any confirmation screen on mobile. 5. If we started checkpointing these users today, we would be locking users out of their account who selected the wrong year without any warning. We should make it less likely that users could do this by mistake before launching. Data 1. 18k users/day attempt to change to a birthday under 13, 15k of which are on mobile 2. 7% of users who are enrolled clear the ID checkpoint 1. Need to understand whether this is due to completion of challenge, eligibility, review capacity, clear rate or something else 2. If we were to start checkpointing all of these users, it would be around a -3.4M MAP/year hit."
