First off, that site has NOTHING to do with Hip Hop. I guess it started off like that, but today that's not the case.
It's not just them though, I think a lot of people (including myself) are tired of the nonsense content out there. The media especially, but Worldstar is right there too. All this violent content is stupid and just desensitizes everyone to violence. It's good that the Zulu Nation wrote to them, but I doubt anything will change since Worldstar is super popular, makes lots of money, and its audience is eats up that garbage.
