It's an unfortunate limitation of the technology that you can never tell the difference between someone not responding to you and not seeing what you typed. I really like the ellipsis-only tell because that is basically the only way that someone can ignore you because of RP and have you know that the player saw the tell.

I find this particularly relevant when asking people to group. Often your enemies will ignore you because they don't want to admit they're you're enemies, but it's also common for people to be out ranking or in a fight and not see your question. So often I have to ask a few times to be sure that I'm being actively ignored, which is pretty frustrating.
