As I was reading the thread regarding a reset... I started to wonder.... HOW does the wilderness end up looking like that? Is it just from a thousand creepers blowing holes or what? Sometimes, it looks like its people mining with no pattern.
It is simply from players mining sand/sandstone and close to surface ores, maybe a few creepers, but 99% player damage.
A few creepers? There was no sand on SMP6 main spawn location... If someone is mining dirt, I will sell them some for 50r/brick.
