Pretty off-topic here, huh?
@mizu
What does this website have to do with players being kicked out of the game? I doubt the site is in any way related to that.
Can we just agree that there isn't a perfect solution? A combination of an anticheat that measures real values like the line drawn to reach an enemy's head (if the line is perfectly straight all the time, it's probably an aimbot) etc., process checks, demo recording and sometimes just experience is the best solution.
Feel free to continue the discussion in a seperate thread, as I don't think the DU4 server thread is the right place for it.
