I think that someone might have been listening, or reading, as your link is gone completely.
Over the years, I have seen several banned. One, 4-5 times under different Adobe I.D's/screen names. Without using names, I'll bet that you can guess who that might be.
I am with you on this one. In "our" product fora, I think that the MOD's do a good job of this. Not sure about some of the others. Heck, going back a half-dozen years, I had material pulled, when a help suggestion DID step over the bounds. It was not until I got the notification, that I realized the implications. At the time, I thought that I had a method to help - I had not fully considered everything, and appreciated that MOD taking care of it for me.
