Re: I'm never Tweeting about my new shoes again
@tzubair: I've experienced the benefits of this firsthand last year when Amex flagged fradulent charge attempts on my account based on the fact that they were inconsistent with my prior purchase history. Im ok with that. I"m also ok with targeted marketing in general because I know that's happening due to the cookies and other tagging that I choose not to turn off.
What frightens me is the idea that my purchase behavior can be lumped into anonymyzed batches and is supposedly de-personalized, but via my own social media statements can still be used by bad actors identify me specifically and, potentially, steal my identity.
It gets even more scary if I start to think about how anonymized health data might be used to be traced back to me.
