Let me preface my suggestion with this explanation.
In June 2019 I will have been a member for six years. For the first five years I tried to avoid using the Ignore function. I think I had a couple of people on briefly during my first year in, but decided it was better to keep an open mind and to see what people had to say...they couldn't be that "bad" after all. We could agree to disagree and still stay pleasant (mostly).
However, about 6 or 7 months ago I got fed up with the constant personal attacks from a member and decided there was nothing I wanted to hear from them again. First perma-ignore. Since then I've added a couple-three more.
The point being that I reached a level of dissatisfaction with those members that I literally did not care what they had to say...period. That's what I believe the Ignore function is for, to completely ignore such members until you decide otherwise.
As a result, I think the fact that when members on your ignore list quote you with the intent to get your attention, it defeats the entire purpose of placing them on ignore if you get a notice that they have quoted you.
Let's be clear, I have no problem with their quotes appearing in member responses, I mean it helps to understand what the member is responding to.
I also have no problem with the "view' option, which allows the member to look at a post if they so choose.
But again, hiding the post while still alerting the member to it? Makes the Ignore feature a bit meaningless.
So I'd like to suggest that the system block all notifications, including quotes, from people a member has placed on ignore. That makes the function work like one might expect IMHO.
