At MinecraftOnline it is possible to collect the heads of players you slay in PvP. You can then place these heads as decorative blocks in the world, taking trophies of your enemies.
To ensure fair play and to discourage abuse, there are certain restrictions in place:
- You can only collect one head from each player within a two-week period.
- You cannot collect the head of players who have been on the server for less than an hour.
- A log of every head you collect is kept, and is searchable by the admins.
- Every head placement and breakage is logged. Stealing heads placed by other players is grief, just as with any other block.
