I think the information shown in this thread has been enough evidence to come to a conclusion. Over the past 4 weeks and 32 posts I've show that excluding booby traps and hit lists  (level 3000+) does not get any kills unless it's on the  (level 407) or  (level 310).
So with all shown we can safely say that 1791381907542816 is a dirty cheater.
Also... Kano were made aware of this guy and his alts months ago, and even shown this thread and have decided it's ok for him to cheat.
Totals for 4 week period
- Main account kills excluding booby traps: 1,888
- Combined alt accounts deaths excluding hitlists: 1,908
