Although Minecraft’s multiplayer offers gameplay on a considerably different scale than traditional MMOs (massive multiplayer online games), independent servers can offer similar functionality on a smaller scale. Where there is competition and anonymity, there will be programs and hacks. I won’t say whether the existence these programs/modifications are justified, but ignoring them does no good. If anything server admins can see what is available and can attempt to take measures against them.
- X-Ray Vision
- No-Clip (pass through any block, including Adminium)
- Fly Hacks
- Speed Multipliers (run and mine faster)
