I don't think I will ever really use the feature. I'm not a prominent figure on CB, don't really post enough to get an in argument with anyone to a degree I would actually become so annoyed with the person that I couldn't imagine seeing anything they post again on my feed. But now I just have curiosity on how it works. If there is a a big discussion on a thread, and two people are going back and forth on it, one of whom you have ignored, do their messages just show up as blank? Just curious.
