Yahoo and AP caught manipulating user comments http://usa.mediamonitors.net/content/view/full/75002

"If this was merely a question of unethical behavior or slanted coverage, that’s par for the course. We’ve come to expect little more from Yahoo and AP or, for that matter, any other MSM outlet. But this is blatant fraud and it’s not just fraud against readers; it’s corporate fraud. Because the number of comments generated is one of the metrics Yahoo uses to cook the numbers to exaggerate user participation and it uses those numbers to defraud advertisers. The same goes for AP, which is obviously complicit in this racket."
