FYI If you go to the link they mention, you can choose to opt-out.. thought it only seems to affect you if you have a Google+ page. I don't have one for my main email, but I do for my SL email, so I opted-out
from my SL account. From the article: " Doing anything from leaving a YouTube comment to starring something in Google Play to giving it the +1 treatment will cause your face to show up on ads.
Here's the link for the opt-out form (again, it only seems to affect you if you have a Google+ page, not just a normal gmail account.) If you click on it and it
you to create a Google+ page, then you don't have one and you don't need to worry about it. Otherwise it'll take you to a page called "Shared Endorsements". https://plus.google.com/...
done not that there is a face to show lol, that said i still has no clue how i got a google+ anyhow they just forced that crap in my personal gmail ;.;
