Actually an auto off method is far from fool proof, it relies on many variables working perfectly, which in the real world, minecraft world, and even in theory never happens.
yes but a manual switch with a timer safety is fool proof, ish,.
Daed the rules are the rules, they have to be followed, if the rules are broken, then the mods will do what they feel is best, even to the point of deactivating machines etc in order to switch them off, and yes damage may occur.
There is no spirit of the rules here, there is the rules, these are specifically chosen to try and help the server cope. if you need clarification ask, but there are no loop holes and rule breaking will be taken seriously, we need to look after all who use the server, as such we cannot permit something for one based on skill, and not for someone else as we deem them less skilled.
