mc10years is a ClassiCube world created in May 2019. During the time of its creation, Minecraft celebrated its 10th anniversary. Hundreds of players joined ClassiCube to celebrate by building signatures on the mc10years world. The world was inspired by a Minecraft Classic world celebrating the 1st anniversary of Minecraft in May 2010. Out of the hundreds of signatures, several were built by the DULM community when the Do you like memes? server was still on ClassiCube. On May 17th, 2019 the world was no longer editable to players.

The world was hosted on a server operated by Dire and Necromancer, which would later be compromised. The owners of the server stated they had lost all their world files, including mc10years. A player on DULM had previously downloaded the world before the incident and uploaded it to dulmCube where it was hosted until it went offline in 2021.
