Limited permissions for users logged in with facebook and twitter I would like to know if there's a way to allow people to log in into my Drupal site with limited permissions with their Facebook or Twitter account.

I have created a website which allows authenticated users to upload images. I have added a voting option which can be used by the authenticated users. I want to allow the people logged in with facebook or twitter to be only able to vote and not upload images. 

I am using Social Login to allows users to login users with their facebook and twitter. Is there a way to set this limitation?
You could use Rules to automatically assign them specific roles, then limit permissions based on those roles.

A few ideas about how to work with rules and auto-assigning roles.
