sounds like it could be confusing if you were reading a response by someone, who was refering to a point /comment made by someone on your ingnore list, you'd have to un ignore them to see what they said :) and, if they reponded the same as someone on their ignore list, about a topic brought up by someone on the third persons ingnore list, the thread could make a really strange read for someone who wasn'r ignoring anybody :)
