How Do I Stop wikiloops From Posting to Facebook?

I hate it when the question is in the title and you have nothing left to write in the post. ;)

Seriously. I log in to the site with Facebook. I don't remember "allowing" wikiloops to post my likes/downloads to Facebook. I'm sure I did, though. How to switch it off?

Click on the "gears "-tab when looking at your profile

Follow the link "To edit the way the facebook app behaves, click here"
