Funcom did provide us with instructions to report the hackers.
Official Servers - Terms of conduct, guidelines and procedures
You have to message Funcom and provide the following information:
* Platform
* Name of the Server
* A description of the infraction being reported
* Irrefutable, veridic proof and evidence to back up your report. This includes, but is not limited to, screenshots, videos, timestamps, names of characters and guilds, profiles.
The problem is providing “irrefutable, vridic” proof. You will need to submit a video showing that the character with the ability hack are doing high-level ability perks that normal characters cannot all do.
Once you have this proof, send a message to Funcom here in their forums.
