Tweet deletion message + UserStream


Hello All,

Im currently hanging with UserStream(C#). In general Im glad of that how it works, however Im a bit puzzled of one thing: Always when somebody mention me in their Tweet I get the notification, but when somebody removes the Tweet in which I was mentioned, I get the notification only when Im following this user.

Question: Is that right? , is that how it seems to be from Twitter side? . Or I should get also the notfication about the tweet removal from the user that Im not following ?

Is there any other possibilty to get information about that that the tweet in which I was mentioned was deleted ? (when Im not following the user which deleted it)

Im new on the Twitter.
