I have an issue that I need some advice on. I really hate it to step on others and expose people. But what to do when a "so called" expert publish an SEO article with absolute nonsense in it on a very prominent marketing site. Should I comment on the article and correct the false statement? And if I decide to do so how do I do it? I mean, it ultimately damages his business and his reputation and will surely start a hefty debate which he will loose. Maybe should just let it be?
