So this is actually a we bit late but I thought it was worth bringing up to you guys since this is a fantastic talking point to bring to the attention of your clients.
As it turns out, starting the 10th of this month (just a few days ago), Google started using personal profile images in Google+ ads. If you like a Google+ page or local business, then your image may show up in your friend’s Google searches along side an endorsement for the company.
While it is a great idea from a business point of view, it is also a horrific privacy breach. Something worth speaking to your clients about — and they may thank you for it.
The instructions for how to disable this for your profile are in the original article which you can find here: http://www.businessinsider.com/google-ads-personal-info-starts-today-2014-1
