I am not complaining about notes or quotes .. 

I am talking about replies and comments .. 

Again to better clarify ..

In "all follows" - I  see notes only from the ones I follow .. but  replies to those notes are from anyone " .. my question is if it is by design or a bug ? ..

Because I was expecting that if I am looking at "all follows " ... Even replies should be only from my follow list .. is it a wrong expectation ?
