For some reason, I see only the purple "ignore" button in places where an ignored user's post should be displayed. That, in itself, is not weird. The problem is that the link on that button does NOT display the otherwise-hidden post, rather, it adds the user to your ignore list, when you click on it. A trifle redundant, and it makes it so that a user has to remove the person from their ignore list in order to see the omitted post.
