he is a hacker . i banned him in mah server. if you allow me to ban i will ban him!
This isint actually true,if he hacked on your server,doesnt mean he hacked on xa too,actually madkiller,your picture doesnt prove much,as there is a difference between bug and hack.
If he falls down and doesnt lose health/armour,then its hack.
Else if he keeps standing and dont lose health,it means bug.
Next time try getting a picture while he is knocked down with no health loss.
