Warned multiple times, kicked once with reason of ping masking he came back claiming nobody gave a shit even though numerous people have been complaining. So I banned him for 30 minutes. Shall see where it goes from here.

His ping in scoreboard never goes above 50 while his ping in console is always over 500.

Users are getting killed by him in a spot seconds after they have left that spot.
