I only ever ignored one person here. In total on the internet I've probably in total got about 5 people on various ignore lists. It takes something exceptional.
Generally I don't put people on ignore, I agree with Oldman in that you can learn a lot from contentious and even annoying people. I'd add that ignoring people is often (in my life if not in anyone else's) about saying "I'm so superior that I don't have to listen to you".
Sometimes they do have a point. I made this mistake when somebody from school who I regarded as stupid pointed out during an exam that I was writing on the wrong paper.
I ignored her compeltely initially, but once it filtered through my big, stupid ego I realised that I had made the mistake and I was the one being an idiot.
After that I learned not to hold myself (completely
) above other people. I'm only human myself.
Ofcourse I did post in another thread "Just block them", there is a line between harrassment and interest. Some people I don't like are interesting, I'll never block anyone just because I don't agree with them, and if some of their verbal 'shots' land a little close to home, there's a lot to be learned from that. I will, howver, block people who harass me. Thankfully, not many people do.
