It's a sad day. Let's not be too happy about it.
As for Bose's question : not all WKD members (there's quite a few of them it seems) have been involved in this. Even though the WKD servers have been shut down, it does not mean that the remaining team members must quit. They are welcome to stick around. Wether they will continue using the WKD name I do not know at this point. That is up to them to decide.
In any case I hope people will not start blaming the remaining WKD members for something others have done. It was a tight group of 5 people who caused disturbances. These have been dealt with - let's end that era here and leave things at that.
