Perhaps a more important question to ask is why there are paid trolls on Yahoo.
Paid trolls include Dirac, Elizabeth, Climate Realist, Talking Bollox, Edward Hitler (banned this week), and a cast of thousands.
They are paid by the Open Society Foundations (link in comments). I have seen them on another website DOING THE EXACT SAME THING THEY DO ON YAHOO.
If you don't believe it, then consider the following:
Open Society Pays trolls to patrol Yahoo Global Warming. They move any/all legit questions opposed to their beliefs. They claim they want to "debate," but then INSTANTLY move opposing questions.
It's quite uncanny that they do this. Go ahead and try it. Make up any question slanted against "global warming." I guarantee you it will be moved to category Abuse & Spam in 5 minutes.
Go ahead and try it. What do you have to lose?
