As I observed the ... breakdown ... amongst certain users of this forum and Luna, I had a lengthy discussion with Luna. I've ultimately suggested, and Luna really likes, the idea of an ignore users list.
Luna doesn't want to leave the forum, but she doesn't want to keep hearing the same abuses. For some of you, I'm sure you have similar feelings or will eventually have if anyone began exhibiting overt rudeness and hostility toward you. Some can take it better than others. Some can't.
So the ignore users list is planned to be added and will block the contents of an ignored user's post from being shown to the ignorer. The person making a reply (through the reply button) will be notified if they're on that ignorer's list, so that they aren't unknowingly replying to someone who will not see the reply. They can still post it, though.
I don't want to rush it too quickly that it introduces new bugs, but I'm starting work on it immediately.
EDIT: Well, maybe I was too hasty. The idea has been shelved for now as per the responses in this thread.
