We can begin right off the bat, at the start (0:02) you're looking down with your crosshair placed on the cement sidewalk and then swiftly lock on to the individual turning the corner in front of you, and killing him. In the next clip, after killing a player hiding in the bushes to the east of construction, you then lock onto an individual running into the north side of construction (0:11). A few seconds later (0:14) you lock on to the same player that was previously running into construction who is now located at the bottom set of stairs. And finally the last one, (any my personal favorite) you lock onto a different individual running into the northside of construction from the massive ditch. (excuse the quality of the video)
I then would like to point out something even more suspicious. You were banned on our server while using an alt account.
