I have had this issue for a long time. If a poster that I have on ignore starts a thread, I don't see it at all. It is like there is no thread on that topic. After I start a new thread, I discover through a third poster that there was already a thread on that.
I am not sure what the solution is (not using ignore is not an option), but if the thread title could be visible, with ' you are ignoring this poster' or something like that- just like we see in the active threads, it will be very helpful. It will avoid those duplicate threads (usually it doesn't go past 2 posts, but is an embarrassment to appear so ignorant of a thread that is in progress)
