/**
* Hooks to deleted_user to perform additional actions
*
* When a user is deleted, we need to be sure the ideas he shared are also
* deleted to avoid troubles in edit screens as the post author field will found
* no user. I also remove rates.
*
* The main problem here (excepting error notices) is ownership of the idea. To avoid any
* troubles, deleting when user leaves seems to be the safest. If you have a different point
* of view, you can remove_action( 'deleted_user', 'wp_idea_stream_users_delete_user_data', 10, 1 )
* and use a different way of managing this. I advise you to make sure ideas are reattributed to
* an existing user ID. About rates, there's no problem if a non existing user ID is in the rating
* list of an idea.
