Just wondering about certain mods. (Not hacked clients)

General rule of thumb is that as long as it doesn't give you an advantage it's fine.

Cosmetic changes that allow you to see potion durations, equippepd armor, durablity, etc without opening your inventory are okay to use. So are things like waypoints mods (within reason) and minimaps (as long as caves and mobs aren't shown), time-of-day changers, animation mods, crosshair mods, chat display mods, etc. It's not like we could even remotely moderate entirely client-side cosmetic changes like that anyway, since they're undetectable through player events (unlike many cheats).

Autoclickers, anti-afk scripts, crafting scripts, auto-tool, auto-armor, auto-loot, etc are not okay. Neither are things like ESP and free-cam/cam-clip type mods (FOV, distance, and rotation changes are okay though).
