The Avast forums have been around for years, and have long had a reputation for helpfulness to users that in many cases has been the deciding factor, or at least one of the major factors, in a new user's choice of avast over some other anti-malware product.
Sorry we can't oblige you with a formal statement of our policies ... as has already been pointed out a number of times, we're here to help users, not to argue with them. If you insist on iron-clad rules, check out places like Wilders Security forums, if you're not already familiar with them; it will be made quite clear to you there that they flatly prohibit discussing, let alone questioning, board policies. We're fairly informal in comparison, and pretty obviously (to most of us, anyway) that works quite well for us.
