> Ditto. These tickets should be easy to auto-close if you force folks to include info about their client.
As a (former) modder, though not for VRChat, I can definitely empathize with this. Code quality with mods is a freaking wild west where modularization isn't really a thing and everyone monkey-patches everything. Supporting your mod/content amidst other mods is in the gray area where the etiquette expects content creators to support their stuff even though there's no "warranty" on the label, so you get significant variance in how demanding players are or how accommodating content creators are.
That said, I don't think anti-cheat is the answer here. Officially supporting mods and driving modified clients down a predictable path where you'll know when and how a client is modded seems like a better approach. Modders benefit from having real infrastructure to work with, and as the game dev you can ask players to turn off mods for troubleshooting.
