If you're "acknowledging" them you're not ignoring them....
You do know what ignore means don't you?
Putting posts on "ignore" is useless You know that....
You don't seem to get the difference between using the software's "Ignore" feature to make someone's post content not readable, and not admitting they post here.
I still see a message informing me that they posted something and I even get a notification.
So in that regard, it's not possible to be completely unaware of them.
But that's not what I'm talking about.
Like I said, I have them on "ignore" as far as the actual content of their posts are concerned, but I know they post.
You can feel free to continue trolling this topic all you want, but I've said all I need to.
