Yahoo! demonstrates once more its stupidity and/or immorality

Hot on the heels of the news that Yahoo helped provide information leading to the arrest of a Chinese dissident, comes news that Yahoo is finally closing down adult-minor sex chat rooms under pressure from the New York and Nebraska attorney generals. I won't go into the details of the article, but it boggles the mind that this sort of thing would have been permitted to begin with. Earth to Yahoo! - sexual activity with minors is illegal! You are a private company, you don't have to allow everything under the sun [or undercover of darkness] to have a forum. And we aren't speaking of a few here - the article mentions about 70,000 different chat rooms had titles that suggested that they facilitated illegal conduct.

I wonder if MSN or Google have the same problem.
