It seems like it is the most toxic part of the forums. People being willfully dense repeating nonsense over and over hoping to goad someone into calling them an idoit to get them banned.
If a person is being a fool the healthiest thing to do is insult him repeatedly ideally. You can see it in a lot of the popular threads people with hundreds of posts who never contribute or even read the subject and just bleat out the same post over and over again. Over moderation allows them to do so. So I would humbly suggest allowing people to call idoits...well idoits.
