It might be better to just educate newcomers to watch out.
Impossible, for the most part, in my opinion. I built a several hundred paged website with that single intention - to help others avoid costly mistakes. The site has helped a lot of people, that I know for sure, but it does not reach everyone. That said, at least 14 that I now know of will be educated by now. Sad to see what levels of dishonesty some people will stoop to.
