I often come across situations where two members disagree strongly with each other and they end up arguing about pretty much everything. So I get asked by member "A", "How can I block member "B" from participating in my threads so he won't troll me and throw the thread off topic"? Now I can tell him to put member B on his ignore list, but that just hides that content from Member A, but everybody else still can read member B's trolling comments, which can be distracting. So, it would be nice if there were a checkbox setting in a user's control panel that says, "Use my ignore list to block those users from participating in threads I start". I think a setting like this would eliminate a ton of trolling.
