I agree that you have no way of knowing if we would grief or not. We know we won't, but you can only take our word for it so it's understandable that you would want to make sure your server is safe. =)
We're reworking that clause - in fact, we're reworking the whole support system so that this issue is resolved. =)
i have not had any memory problems but i do have problems with the server maxing out my cpu. granted i only have a Pentium 4 2.4GHz single core with 1.25 GB ram. it only seems to happen when people are editing large maps (ie larger then 512 cubed). it gets behind in saving the maps so it lags people joining those maps. norm if everyone leaves the maps for a few min then the server catches up and everything is fine for a while.
We have released some new versions of Hyvebuild, go check them out. We've made a in-game method of backing up and restoring maps, along with binding. (Thanks Goober!) We have also removed Elites, and fixed some bugs.
Even better yet, hold off on going to that one. A official Hyvebuild site is launching in the upcoming days. We'll shift the official support over to the new site and our IRC channel. Thanks for waiting.
