Unfortunately Killa didn't quit Blockland forever from that email he sent to Badspot saying he'll quit Blockland forever.
Oh and when Killa said to Zaem that he was a better builder, he is so wrong! =P
When he was on that family RP that I banned him on, he built a airport that didn't let others get in and he only had roads on it. He said he was done with it but then I commented the problems about it. He then got pissed off and said well its better than your builds. He used mainly 1x1x5 bricks plus he then just said he saved then told me that he'll just load it on his server host the family RP.
Well this just lets me know now that the only thing that Killa can try and hack is stealing others saves. Plus he tell others that 1x1x5 bricks is spam but even he uses it.
