Seems odd how extensive some ignore lists are. I think I have one person on mine from years back. The rest I can ignore if they post their usual ramblings, but even those I know I disagree with have some points at times.
I’ve had two people on ignore only I never knew it until I was examining my profile in order to change my signature or something like that. I think when I have scrolled on my tablet I have accidentally hit ignore! I know I hit like accidentally sometimes, too. I even have this horrible habit of falling asleep with the tablet in my hands and God knows what I click then! Last night after reading this thread I checked and once again found I had ignored someone without ever meaning to. Oi!
