Primal uses this to publish the list of suspected spam accounts (detected by our spam detection algo), so that other clients can use it - if they wish.  

 Is the cache service doing that or the client? 

 Not exactly the cache service, but yes - this is being done on the backend.  

 That information sharing between apps is so beautiful it brings tears to my eyes… 

 The censorship is so real, I can almost touch it 😍
