Regarding Ignoring Users:
Suppose that User "A" ignores user "B".
Suppose that User "A" does NOT ignore user "C".
Suppose that User "C" does NOT ignore user "B".
Suppose that User "C" quotes something posted from User "B".
Will User "A" see the material from user "B" through the quotation from user "C"?
Also ...
From User "A" 's point of view, will user "B" 's post never appear, or will they appear with a message like "You are ignoring this user."
