Nocom

Nocom was a coordinate exploit used by Nerds Inc on 2b2t from July 2018 to July 2021.

A patch to PaperMC caused the following exploitable behavior: telling 2b2t "I am digging the block at XYZ" causes 2b2t to reply with "no you can't, that's too far, put it back as obsidian" if XYZ is in a loaded chunk. If the chunk is not loaded, 2b2t does not reply.

In other words, you can just ask if any chunk in the entire map is currently loaded, and 2b2t reveals if it is or not, from if it replies or ignores you claiming to have punched a block within the chunk.

The patch was intended to only allow you to punch blocks within your render distance, but due to an oversight, the Paper developers allowed you to punch blocks in anyone's render distance.

From July 2018 to late 2019, a spiral scan was run from spawn outwards into the millions, logging any chunks that were loaded. This would find players at their bases.

From March 2020 to July 2021, players were tracked along their journey to their base. They were caught along the highway, then an automated system would keep up with their journey by following along with chunks loading and unloading around the target.
