I also had ignored a poster and thankfully the whole thread is being ignored. But it looks like that might be because the ignored poster is the one who started the thread. Is that the case?
I did sign on using another machine and saw the whole thread because I wasn’t signed in. I understand that. But unlike Eliza, I don’t sign out when I leave. I just close the browser/page. So when I go to the discussion I don’t see the thread, but I get a message that says that “this thread is being ignored because you have ignored ______”
Wasn’t it the case in the old board that you could “delete” or “ignore” whole threads?
