Here’s a scary reminder that your digital identity has three layers, and you can only protect one of them:

The bad news is that when it comes to your digital profile, the data you choose to share is just the tip of an iceberg. We do not see the rest that is hidden under the water of the friendly interfaces of mobile apps and online services. The most valuable data about us is inferred beyond our control and without our consent. It’s these deeper layers we can’t control that really make the decisions, not us.
