Carl,
The world has been of fools, morons and suckers since eternity and those seeking to benefit from them one way or another.
But we are not all incapable of differentiating between good science and non science.
Even (some) kids at school these days get lessons on how to work out what is reliable info (or not) on the internet.
They are given half a dozen diffreent sources of information about the same subject and then they have to work their way through it and ocme to a conclusion.
Maybe we all need to get our internet filtering drivers licences before we are allowed install our first web browser !!
There is a site
http://www.crank.net/
Maybe that is good place to start reporting them.
I dont have a solution, but I suspect none exists - it may be that you will have to rely on the resilience of the human species for that, we all learn in different ways and for many that is the hard way !
Keep up the good work
