The Hypixel Help Desk cannot process reports.
You can report rule breaking while online on the Hypixel
Server, using the command /wdr. This will have
our anti-cheat plugin check the player. Please understand that
this may fail.
example: /wdr Tactful
A stronger way to report people, with a very high chance of success, is to report on the Hypixel.net forums's "Report Abuse and Hackers" section.
