# Farms & Responsible Building

<p class="callout warning">**⚙ BUILD FOR THE SERVER YOU SHARE**  
A machine is not successful if everybody else pays for it in lag. The server is already trying to stop their hearts; it does not need help stopping the ticks.</p>

## Practical limits

- Keep passive mobs to **50 or fewer per chunk**.
- Avoid excessive item streams, villagers, minecarts, hoppers, portals, or always-running redstone clocks.
- Shut down farms when storage is full or nobody is using them.
- Do not build AFK farms or automation that bypasses intended play or harms performance.
- Ask staff before committing to an unusually large technical project.

Staff may pause, limit, move, or remove a build that threatens stability, even when every individual component is obtainable in survival.

## Public farms

Public farms belong to the community. Replant or reset them, do not empty every reserve, and do not AFK in a way that prevents others from using the farm or warp.

---

## The landscape

Avoid floating treetops, lava casts, pointless craters, abandoned scaffolding, and visible resource scars. Restore temporary work sites and replant trees where practical.

<p class="callout success">**Good engineering is survivable:** efficient enough to be useful, controlled enough to stop, and tidy enough that it does not become the next server-wide incident.</p>
