How about this:
For those people so concerned about rock stealing, there should be an optional "Mining Crate" that they can buy in the shop for let's say 15 gralats that you can temporarily store the rocks in.
You place it down like on the outside of the dirt and have the opportunity to claim the rocks by pushing it beside the crate and then lifting the rock. It'll then safeguard the rocks to be mined until ready to be used, and no one can get it out except for the owner. When empty, the owner of the crate can just pick up the crate so it disappears into the inventory.
It'll have a 5-10 rock limit (random since ore naturally comes out in different sizes) that can fit inside it. After 50 uses or 1 hour of idle time, the crate 'breaks down' and the rocks inside it, if any, disintegrate.
The script and implementation would be 'fairly' simple, and it'll ease some of the problems.. i'm kinda stumped for more ideas with this, so anyone care to help out?
