It's been a very interesting month or so, considering 4chan is being blamed for the celeb photo leak and the gamergate harassment. The two of which are not the fault of the site itself, merely a rogue faction of users that don't represent the behavior of the whole. There has been a push to make 4chan "family friendly" which sounds ridiculous but go to /b/ right now and the gore, racism and porn has been curtailed.
I don't feel like there is going to be any investigation on how easy it is to bait the media with a domain name and simple hosting, because the same outfits that got hoaxed all benefited from the generated outrage.
Or just another way to get publicity...
4chan is not like Silkroad. If you "kill" 4chan, there will be enough alternatives.
Even killing Silkroad didn't kill Silkroad. Other alternatives popped up after the FBI shut it down. For a site as big as 4chan, killing the main site would only serve to disperse its users across the Internet.
