I have talked to flamingfury that it is allowed to talk with people on Teamspeak, Discord etc. as long as the players does not reveal and information that would change the outcome of the round, because he apparently did not know that. However the RDM part was still valid even if it was your friend because you shot him for no reason. No further action is needed and flamingfury now knows this and he made sure not to do it again. Your warn will also be edited to just RDM.
Thank you for reporting and have a fun time playing!
