I need to customize pipeline for registration through the social networks.
In case if user doesn't provide email, I want to revoke token and after that redirect user to specific page. I know, that there is SOCIAL_AUTH_LOGIN_ERROR_URL option in settings.py, but I don't want to throw error and redirect him to common error page.
So, can I completely stop pipeline (I mean not only suspend for further usage, but break, destroy, kill, finish ahead of time) and redirect user to specific page without throwing error?
