About Face?

Apparently, Facebook feels the need to press you the user, into advertising, whether you like it or not.

As I understand it, if you buy a Cormac McCarthy novel off Amazon.com or some new outerwear from L.L. Bean, an ad will pop up on your friend's page with whatever picture of you has been downloaded to Facebook to demonstrate your love of the product to your social network.

This could be okay, as I like to know what things are happening in my friends' lives, but I don't see where the restrictions can be limited. If one of my contributors happens to buy something inappropriate online, I don't need to know about it (or have my imagination run amok with how these "things" might be used).

Thoughts?
