I started to see this slippery slope about a year ago, saw my name (and face!) appearing in advertisements on friends feeds, saw messages from me appearing in my friends feeds without me being (totally) aware I was about to spam them, saw timelines of my entire life with pictures that other people had taken and I was only vaguely aware I had noted I was in them.

I just deleted my facebook account.

With the exception of technical friends who have children, and are trying to find an easy way to share pictures with the grand-parents/inlaws/family, the majority of my colleagues in the valley have just stopped using, and in many cases, have deleted their facebook account.

End of problem. No more intrusions of this kind.

Not the solution for everyone, but it's a pretty straightforward mechanism to eliminate this problem, and, in my case, really cost me nothing.

Now, if I had to delete my Amazon account to avoid those tracking ads, that would be a whole new level of pain. I don't know if I'm ready to do that, yet.
