With my experience as a Cop on a Tekkit server that I used to play, I really enjoyed one plugin. Hawkeye. You may have heard of this, or even used it before, even though I haven't had a whole lot of experience with LB, I think Hawkeye should replace it. Hawkeye can tell who set fire to things (kinda pointless on this server), who stole from chests + the data values and amounts, of the items stolen. I don't know if you agree, but I had to throw this out there, as it may be able to benefit the server.
