Hacker Valley is not actually Hacker Valley. I'm there and there are at least 5 other houses of people friendly who dont hack and dont KOS.
Although I am sure you are right about the hackers being a large part of the issue. Between them collecting like mad and people placing 5 doors on every entrance and window (especially seeing as every wall has to be a window) it all adds up to bringing the wipes forward.
Although last night Helik was on and said that they are going to be updating soon and should be taking care of the hackers :)
What's your name in-game? :p
It's called hacker valley because it is a typical target for hackers, at least yesterday there were a lot of hackers targeting that valley. I know the fortress Otto was talking about, there were a few hundred doors around that giant staircase, they must have used a dupe exploit.
