Is there a good reason why CCP continues to even use Twitter in the face of all this abuse? I'm not suggesting that the assaulters are in any way justified in what they're doing, but leaving Twitter and finding different ways to communicate with people seems like an obvious solution to the problem. Maybe it's harder for me to grok as someone who never really got into Twitter in the first place.
