Here's what I KNOW actualy happened;
/b/ alliance (which is mostly from 7chan) got angry and disbanded. After that some of them began spammnig the forum, then the forum got raided by *****.
After that, someone managed to steal the source code and you can download it. I am not going to say where since it's stolen property.
In the mean time people are moving to LunarWars. It's simialr to CN but still small. It's nice though. Of course people there (and some of those coming from CN) are very worried that the CNers might bring the all the crap CN drama to LW and ruin it.
