Upon review of users connection information there are no users with ban history exceeding a one day from his connection location, so his comment about IP may have simply been trolling. User averages about 1/3rd of shots hit, less than 1/5th head shots. User has alias' on the public server starting in late 2017; review of account history does not present sufficient grounds for a ban without some form of a demo to review. While Demo's recorded within the server using the game client are still crashing, a demo recorded utilizing 3rd party software is sufficient for the Command Staff and Military Police to review evidence presented against a user. I personally recommend either OBS or the Windows 10 built in recording suite as they both have minimal footprints in regards to resource utilization.
At this time the user will not be banned unless a higher ranked officer or senior MP is able to determine what account this user is circumventing a ban for, or a demo is able to be reviewed to determine use of aim-bot.
