Not to be 'that guy', but there is a danger with copy/pasting wholecloth. Since the material is usually copyrighted, it opens up the possibility of KB getting a lawyer letter asking to remove the posts. It's also a courtesy to the OP to let people go to their website to read the material. That way, the original site gets the clicks and the resulting ad revenue, which is a cheap and easy way to show thanks for the content.
Just my $0.02.
