I agree with you that some folks may have been banned before they should have via the AP system. As such, if such a case presents itself, let one of the mods or myself know about the situation and we'll take a look at it on a case by case basis. We haven't decided how we're going to handle the AP system yet, and are still weighing the good against the bad. If you have thoughts about it, let us know (and yes, I've read the many discussions on the matter that have come up in the past--it's obviously a hotly debated subject).
