idea for a possible event:

++TRANARCHY WEEK++

basically admins make a backup of the world as it exists on scheduled date, then they do all the following:
-disable deathchests
-disable /tpa /spawn /home and /back commands
-restore firespread, tnt, mobgriefing, crystals, lavaflow etc
-maybe disable /maptool command as well to avoid 'p spam

then the admins fuck off and let us kill each other and blow up the map with zero consequences until seven days later they return and restore the save.

I think it could become a gemmy Mad Max post-apocalyptic wasteland.
