I don't know if anybody else noticed but I haven't seen this anywhere, so I figured I'd go ahead and post it..
I've been botting space missions for a while and it seems that when they released 1.2 they added social points as a reward to the bonus missions of space missions.
Not very much (2 social points per bonus mission is what I'm getting) but it definitely would add up if you bot-- after doing space mission botting to lvl 41 I have about 580 social points.
EDIT: Actually I think this is with any bonus missions when you are in a party, and you must be in a party to get the social points
