I hear ya. Unfortunately, that's one drawback to public forums. There's no prerequisites in order to post anything you want. Misinformation can be spread so quickly.
That's why I say, probably all too often, always learn from reliable sources and cross reference any info you receive before taking it as true and before putting anything into action.
Abraham Lincoln was once quoted saying "Be careful what you read on the internet, 80% of it simply isn't true."
--------> if Honest Abe said it, it MUST be true.
