A few weeks ago Twitter started sending emails saying so-and-so has tweets for you. Problem is, I've created an enormous number of Twitter accounts over the years, most of which are long-forgotten, that follow no one. So presumably their robots have no way of knowing what this non-existent entity likes. So I get the dregs.
Here's an example.
News about super celebs, TV stars, famous athletes. Mostly grunts and snorts and news that I've already read.
