I split this topic because it was unrelated to the original one.

To answer your question, just use the command /lb toolblock and place the sponge you get around in broken areas, or hit broken blocks with it, to see a log of what happened to the block you hit or space that you placed the sponge pop up in your chat box.

Screenshots of these logs are extremely helpful in determining griefing responsibility, and are an invaluable asset to us in the effort to administer proper justice.
