If people are already creating the fake paperwork, then the idea of secrecy as a deterrent is a failure. Information sharing is a better concept as it will make people more aware that "anyone can get that". Secrecy has created the value of fake papers. I imagine there are people that want the information kept secret so that no one knows what they are doing. Do we now have a Moparts CIA? Who is the lack of knowledge benefiting? The dishonest. Learn a lesson from our government, the truth will eventually get out when you try to hide it. The people that post here make an easy target when you can't do anything about the ones that make the forgeries. So, if you don't want to share your secrets, don't respond to the post with attitude. That benefits you and no one else. It is a control thing. Imagine, all this over a valve cover mark.
