If I have to constantly clean up after AB, then I will remove him. This platform has stronger tools where I can remove people from threads where they don't belong. I can keep users in the lanes where they belong. If he disrupts one of your threads - I can take him out of it. Of if I have to keep doing that, when I will have to visit a permaban.
Boards that are just preaching to the choir usually stay small. He is the one that ultimately decides whether I remove knuckle heads or not. The decision was reached via a staff discussion to remove the loons. They don't foster dialog. We will have a discussion among the staff about users like Artie and Danoh. Meshak is gone, because she became a needless distraction. I do suspect if they are a persistent problem - like Meshak they may wear out their welcome.
