I had the same "shock" when I read this. One of the dumbest thing I've seen in FoE so far. Knowing that someone ignores you saves a lot of frustration with sending message and expecting response. Gamers are weird, can "ignore" for no reason whatsoever, can even click "ignore" button by mistake in hurry and never notice. So if that change means you can't see who ignores you, that is not improvement at all. In that case I would appreciate MOD giving rationale for such a change.
The whole message system is a total joke already even without this.
