It's much easier for bankers and con artists and agents to argue with a lone person or two on a forum, but try arguing with a half dozen articles that all say the same thing from a half dozen different perspectives, from a range of years, gathered from across the internet.
Likewise, it's much easier for credulous fanatics to cite half a dozen articles from conspiracy-theorist web sites than to argue against hundreds of articles, books, speeches, etc. saying something else from hundreds of different perspectives, over a range of decades, gathered from real life. And it's much more comforting to tell yourself everyone who disagrees with you is uneducated, trolling, or an enemy agent than to face the possibility that you're wrong.
