hook_user_cancel($edit, $account, $method)

Act on user account cancellations.

The user account is being canceled. Depending on the account cancellation method, the module should either do nothing, unpublish content, anonymize content, or delete content and data belonging to the canceled user account.

Expensive operations should be added to the global batch with batch_set().
