So you have this great house right? but you leave the server and when you come back it looks like creepers had a party at your house and they took all your stuff...which sucks.:(.But there is a GREAT way to not make that happen. First, you need to find a place far away from where anyone else lives.Second you need to dig down about 10 blocks and you clear out the blocks around it so you would have an under ground house.Third put a block over the place you want to have a house and you need to remember this so you can find your house if you cant do ./f sethome(if you can, dont place a block, be totally enclosed) then the chances of getting griefed or raided are WAYYYYY smaller. i hope i helped have fun:)
