If a manager seems not to be handling your unban request, it does not mean he is actually ignoring it, so I kindly ask you to be patient during the whole process. Spamming in order to receive an answer won't do anything else than increasing the time to get a response. As far as this unban appeal, it seems you have explained how facts went, as well as administrator Nexus_Riggs did. What I would wish to know is: why have you headed towards the officers if you were in an open space with all the freedom to move in a different direction? Nexus has, additionally, advised you to report a player if he deathmatches you, so I may assume that your act is a sort of revenge towards a player who was there at the organized patrol. If it is like I assume, it is better to say the truth, instead of continuing to investigate something which will, only, increase the time for a possible unban.
If Nexus has anything else to add, feel free to do so.
