Short, and meant literally. If something here is ambiguous in the moment, ask a member of staff rather than guessing.
Bugs are not exploits until you use them twice. Find something broken and tell us — there is a feedback form on the Home tab of the F3 menu. Find something broken and farm it, and that is a different conversation.
Both go to the same place, and both are read by a person.
Screenshot or a clip if you have one, plus roughly when it happened. “Someone RDMed me at some point” is very hard to act on; a name and a round is easy.
Say what happened from your side. Appeals are not automatically refused and staff do get things wrong — but arguing it mid-round is the one thing guaranteed not to work.
