Craig Newmark, founder of Craigslist responds on the problems caused by security company Authentium in blocking Craigslist on Cox networks:

"First, I want to thank members of the Cox abuse team, I've worked with some myself to go after bad guys. I honestly have no idea as to the role of Cox management in this.

"I guess I'm real disappointed in Authentium, it's taking an extraordinary amount of time to fix this. As you see, it'll take at least six months to just start to deploy the fix."
