We can currently ignore people, which is great.

Can it be made to automatically ignore replies of people quoting those on your ignore list as well?  It would be "Ignore User" and "Ignore User and Replies to User" for the ignore options.  Same options, just if the quote is by somebody on your ignore list, the reply is greyed out, with the option to read as well.  That would be Ignore+

Ignore++  is a bit extreme and adds anybody quoting somebody on your ignore list to your ignore list.   This would be the "Ignore user, and add anybody replying to ignore onto ignore list" option.

I'm only adding this last ++ bit to the request so I can compromise later and say it's OK to not have just the first two.
