Nick Detector SHOW /NICK USERS IN PREMIUM SERVERS
It may not show the absolute truth.But usually true.
Nick Detector is a lightweight client-side mod for Minecraft Forge 1.8.9 that checks whether player usernames exist in Mojang’s official database. If a username cannot be found, the mod displays a red [NICKED] tag next to the player’s name in the TAB list.
Features Client-side only (no server interaction or packet modification)
Uses the official Mojang API for username verification
Ignores rank prefixes and guild tags
Asynchronous checking system (no FPS drops)
Smart caching to prevent unnecessary API requests
Lightweight and performance-friendly
The mod analyzes only the original Minecraft username obtained from the player’s GameProfile. Rank prefixes (such as MVP+) and guild tags are ignored to ensure accurate name validation.
Note: This mod only works on premium (online-mode) servers. It detects usernames that are not registered in Mojang’s database. Valid premium usernames cannot be detected.
