Banning admin here, so your friend was banned as he killed someone over a stolen lobster, as can be seen in the clip. Stealing a lobster is not grounds to kill someone, that is just blatant RDM, he also has 5 previous offenses of RDM so he should have a very good idea of how the rules of the server work at this point. In no way is that RDM bait either so that argument is invalid.
