User deletion is always a sensitive task for two key reasons:

It can involve the deletion of content or changes to the content's authorization.
There are two open core issues: potential content regressions (Issue 3089747) or errors in the ownership of revisions (Issue 2977362).

For these reasons, it is crucial to perform this action in a highly controlled manner.

This module allows you to enable or disable the two actions associated with user deletion:

Delete the account and makes its content belong to the Anonymous user.
Delete the account and its content.

This helps prevent possible disasters in the production database.

In complex projects, the recommended process is to first test the user deletion in a staging environment. If everything works as expected, you can then proceed with the action in production.

How to configure

Go to "/admin/config/disable_user_deletion/settings".
Select the actions would you like to disable.

Disable drush commands

To apply these restrictions to Drush commands, copy this code into the file "drush/Commands/PolicyCommands.php":

/**
  * User cancel policy .
  *
  * @hook validate user:cancel
  *
  * @throws \Exception
  */
  public function usercancellValidate(CommandData $commandData) {
    // Only validate if module 'disable_user_deletion' is enabled.
    // @phpstan-ignore-next-line
    if (\Drupal::service('module_handler')->moduleExists('disable_user_deletion')) {
      // @phpstan-ignore-next-line
      $config = \Drupal::config('disable_user_deletion.settings');

      if ($config->get('user_cancel_delete') && $commandData->input()->getOption('delete-content')) {
        throw new \Exception(dt('The option to delete users has been disabled, please contact the technical administrator.'));
      }
      if ($config->get('user_cancel_reassign') && $commandData->input()->getOption('reassign-content')) {
        throw new \Exception(dt('The option to reassign content has been disabled, please contact the technical administrator.'));
      }
        }
}
