Firstly this whole story of not being able to find the screenshot etc sounds lame, if you have enough knowledge to go on the internet and play games, i think you should know what a screenshot is to the least.
Now on to the demo, once drn goes into spec to analyse his gameplay, you get many weird kills where you cannot control the aimbot, doing what i like to call "lazy bursts" = not really aiming accurately at target and shooting bursts for lucky shots. Well in this case the lazy bursts are more successful due to his aimbot which you cannot seem to control, shaking his aim throughout the demo.
A really strange kill that made me believe you are using aimbot is when you were in combat with Fawkes. You jump on the box, which would normally affect your accuracy but you shoot a little burst and seem to get a HS through the box, only damaging Fawkes. Looking at the direction you were aiming, that should not have been a headshot and it cannot be luck in my eyes. Also the way you move around throughout the map is quite noobish, you move around exposing your whole body most of the time, not carefully looking around corners and running across the map with your aim not at head height, just giving lucky bursts to get the kills. Judging your score with your playstyle, i do not think you can manage to get such a high score without some sort of unfair advantage.
That concludes it from me since i do not want to repeat what everyone else has said from my analysis.
