Reason why ignores shouldn’t actually be 2 way, because this can cause for harassment and more bad cases of trolling from people within the forums. Case in point:
If the ignore switched to being 2 way, and lets say I had a problem with someone on the forums, I could chose to ignore every forum user, and then start outright using the forums to harass the users or troll them. And since the ignore is 2 way to where they can’t see my post, it means they won’t be able to report it for Blizzard moderation.
I think ignore should only work 1 way, be be account wide.
