this plugin does what it says: if players place a block or a bucket down, it will be reverted to air after 15 seconds. make sure that fluid spreading is off and allow-break as well and that people don't have permissions to place any falling blocks! (download
worldguard for that)
the plugin is intended for our pvp server. if you want to test it out before you download it, join
axo.bar and click on technoblade to go to our pvp server.
if you want us to add more to the plugin, let us know! we'll respond asap!
