Used to be “Squabbles”. It, Lemmy, and Discuit were three of the major Reddit alternatives thrown around during the Reddit protests.

This was so bad it actually prompted modders to backport all of the 1.19 features to 1.18.

This has been a thing for every major modern version. Its faster for a single enterprising dev to backport things than for the entire mod scene to update to a new version. I distinctly remember playing Blackgear’s Caves and Cliffs Backport on 1.16.

There are, however, Forge/Fabric mods that completely remove the reporting system.
