That is a feature that isn't available yet (so just an idea), right? I have never seen a brighter Ignore button here so I was wondering if it's a thing or just a suggestion.
There used to be a feature where if a user was ignored by multiple users it would have a shading of yellow/orange depending on the amount of users ignoring them. It was removed.
That must have been before I joined. If it was removed because it can easily be abused to target specific users, it might be possible again if the "ignore power" depends on earned Merit.
I'd prefer to actually push for a optional feature of sorting posts by merit
Although I'd like to see this implemented, I can think of several reasons why this is a bad idea. Merit sources for instance would overlook newly made good posts.
