Here's what you'd see back in 2012 if you were signing on to Obama campaign's Facebook "I'm In" app, which they used to garner 1M supporters' trust, and then harvest FB social graph. 1/n
First screen, from Obama-Biden home page 
Or, log-in prompt if you were on Facebook.
Useful nudge, showing you how many of your friends were already in Obama campaign app.
Another nudge screen.
Here's the Obama permission page. Note that it only says your friends will only receive messages you choose to send them. That's good. It says nothing about information that campaign might obtain. That was bad.
Here's the next screen you'd see if you clicked "allow." Does this read like a disclaimer to you?
After you clicked "allow," you'd see this screen which in fine print explains the range of data you were giving the campaign access to.
Oh, you are wondering if the Romney campaign did this too? Why yes, I have those screenshots as well. Here's "MyMitt" (a pale imitation of MyObama).
Nicely, MyMitt invited you to join via various social networks, including AOL.
Here's the Romney Facebook login button. They didn't push this as hard as Obama campaign.
And yes, once you gave them permission, you'd see this screen telling you what you were giving up.
The bottom line: If you aren't paying for something online, it's because you're the product being sold to someone else. Read "terms of service" and stop believing that "privacy policy" means your privacy is being protected. It's not. (end of thread).
