"Expiration dating" is a Black Mirror plot line come to life

We've quickly come to accept that brands know as much about us as we know about ourselves. Facebook serves you ads for cat food after you talk about getting a cat.

So it stands to reason that fewer pics of you with your significant other on Instagram could signal to apps and brands that your relationship may be coming to an end.
