I found the idea of an instant ban due to ignorance of the rules to be excessive. I stopped arguing about that once I was informed that warnings would be employed and there was an opportunity to plead for leniency if one were simply ignorant. I found that to be a satisfactory way to deal with it. But I agree with not spreading knowledge of bugs and instead reporting them to the developers. If you know enough about the bug to know that you need another person to help you learn about it, you know enough to fill out a report ticket to bE.
