Oh, I agree: we get all types out here, and some of them might actually get the help they need.
As far as colloidal silver is concerned, my wife and I have a bit more experience on the subject than most. The Czarina runs a jewelry store in Dallas, and she gets at least one person per month who wants to come in and buy large amounts of pure silver wire. Now, she can tell right off the bat that these are colloidal silver nutters, because nobody uses pure silver for jewelry. It's just too soft, so "sterling silver" has a small amount of copper and zinc to add strength. The only people who need pure silver wire are those making their own potions, and she promptly sends them on her way by telling them "Sorry."
