Does the ignore feature completely wipe out the person you ignore's message? If so that could get confusing.
EXAMPLE:
Willie: We bought a whole tank of propane.
and let's say Willie ignored Zeldasbiggest fan, and can't see his post.
ZELDASBIGGESTFAN: WHAT ARE YOU HANK HILL :retard
Now Pub Lover, who is too lazy to use the ignore feature, replies to zelda
Pub Lover: I'm depressed that I know who you are talking about
Willie: Wait. WHUUUUUT?
END SCENE. You see what I mean?
