I would be ok with a semi-permanent chaos server! I have a very left field idea though.. What if the chaos maps weren't limited to old reddit minecraft maps? What if we approached a couple other minecraft communities with relatively big worlds to see if they would offer up one of their worlds to chaos? At first it kinda seems insane, but think about it. The other minecraft community could have a short blurb at the chaos spawn about why minecraft redditors should check out their server. Further, reddit server players (and hopefully the other server's minecraft players) would troll around the world wrecking everything, and thus seeing all the cool builds the other minecraft community made. Both the reddit minecraft community and the other minecraft community would get good exposure to each other. It wouldn't need to be a permanent chaos server either.
This is probably infeasible, too much work to arrange, or just a dumb... but.. I thought I'd chuck it out their anyway
