Forget a user

DELETE
/v1/risk/users/{user_id}

Call this when you delete one of your users: COSS deletes what identifies them in the environment (their mailbox, fraud reports, and the user id, email address, IP address and user agent on their assessments). Decisions and reasons stay. Forgetting a user COSS doesn't know succeeds too.
