The IP on my server changes every night since I run it from a comp at home, so only the people that I give it to that day can get on. Also I save the map after every session. And there's whitelists and so.
Sure, some dicking around happens, but the people I play around with realize that there's a difference between a bit of fun and permanent damage. I've only ever been locked in my basement via obsidian when there was a diamond pickaxe available, for instance.
