I just went nuts trying to find the rules that I said were "posted below" and couldn't find them anywhere. You have to click in the "reply" box to see them. Which makes me wonder if that might be part of the problem we have with newbies, they don't see the rules until they're ready to take the plunge and make a post.
Maybe it would be a good idea to have the rules at the top of each page instead of invisible until someone is about to post. Or even putting them between the Subject and the Message might draw attention to them, maybe with "do not reveal the clients" in a flashing font or bolded or a different color to draw attention to it. (And maybe adding the rule, "Do not ask who shops a business you are interested in; nobody is allowed to tell you."
Time to build a bigger bridge.
