I will think about adding a name based antigrief system. I came up with some advantages and disadvantages, if you can see any that were not mentioned below then I encourage you to post it
Antigrief based on a player's nameAdvantages
- it's easy to detect the griefer when spam blocks are involved,
- while spam blocks are very annoying they don't lead to the house flood.
Disadvantages
- one can spam block an interior of somebody's else house,
- a new player is able to spam one that already played for a substantial time on the server,
- the system is highly dependant on Ops.
