Not only did some one grief my XP farm (smp1 wasteland) but they set lava traps for me and I died twice trying to rebuild. I have a pretty good idea who it was since they muscled into where I was working on it 2 days ago. Really tried to push me out. I just joined (iron) today so I could hide. My farm produces 30 levels in 22 minutes so I hate to give it up but I can't stay for this.
