Hello,
Since Wolf said we don't have any protection plugins for players to protect their homes, I suggest we get PreciousStones or ProtectionStones. They are similar, PreciousStones is the exact same plugin as the ProtectionStones but with more useful things.
PreciousStones
This plugin let players protect areas with different kind of blocks. But it also have blocks like God Stones, which heal/feed/repair your tools slowly. Or peacekeeper (which we don't really need since pvp's off). You can configure to use another kind of block, like if you don't like to use a sponge, you can use something else instead. "You can mix and match over 80 different kind of flags to create your own customized PreciousStone that will do just about anything." It also have economy support so that you need to pay to place a PreciousStone, but when you break the block, it'll give your money back.
ProtectionStones:
This plugin to me is like a smaller version of PreciousStones. It only have 3 available stones that only protect an area. It is incompatible with PreciousStones since they both use the same command (/ps). This plugin require WorldGuard.
Thank you for your time.
