The fastest way is the in-game Report button: right-click the player's portrait or name and choose Report. In the Customer Support window pick a reason:
Cheating — Hacking or Botting.
Gameplay Sabotage — AFK / Non-Participation, Intentionally Feeding, or Blocking Team Progress.
Inappropriate Name — Character Name.
Add any extra context in the optional details box and click Report.
If the report needs evidence a GM can review (a screenshot, a video link, a longer write-up), also open a Submit Ticket with type Other. Include the player name, realm, what they did, and roughly when. GMs investigate in the order tickets arrive; you won't receive a play-by-play, but action is taken where it's warranted.
