Fortunately, Google has made it supremely simple to opt out of its impending ad campaigns. Go to this link on Google and scroll down to where it says: "Based upon my activity, Google may show my name and profile photo in shared endorsements that appear in ads," uncheck, then save. That's it! You're safe. For now.
- Friends of friends = strangers. Be really careful about that "friends of friends" visibility option. Honestly, we can't think of an incidence when the optimal setting would entail sharing your content with people connected to you only by virtue of mutual friends. It's a weird gray zone and huge slippery slope that may invite a few thousand more prying eyes than you anticipate. As far as we're concerned, doing so is the same as going full-on public (which is fine, as long as you're fully aware of the risks of that level of visibility).
