Description

Adds a method to report potential fraud:

1. Gets all labels created by the user in this project
2. Creates a Trust & Safety case for the user (MANUAL event type, HIGH severity)
3. Removes the user from the project (prevents creating more labels)
4. Deletes all the user's labels

Note

Implements a fraud-reporting flow (create T&S case, remove user from project, delete their labels) and adds SDK support to delete project memberships and filter/delete labels by creator.

• Alignerr:
  • Fraud reporting workflow in libs/lbox-alignerr/src/alignerr/alignerr_project.py:
    • report_fraud(user_id, reason, custom_metadata) orchestrates: fetch user labels, create T&S case, remove user from project, delete labels.
    • Helpers: _get_user_labels, _create_trust_safety_case, _remove_user_from_project (uses client API), _delete_user_labels.
• Labelbox SDK:
  • Client: add delete_project_memberships(project_id, user_ids) GraphQL mutation to remove users from a project.
  • Project:
    • Extend labels(..., created_by=None) to filter labels by creator.
    • Add delete_labels_by_user(user_id) to bulk soft-delete a user’s labels.
