I would ignore being on someone's ignore list. All it means is that you cannot post in a thread they start, nor can you quote/reply to them in other threads. You could still reply in other threads, just not by official name.
I know sometimes i get a little exuberant or stuffy in my posts and it rubs people the wrong way and they put me on ignore. Hey i gotta be me! But they can protect themselves from my triggering them by using ignore, so win-win. I be me and they be them.
