Eins, unban him.
And about you, sir, you should watch out what mods you use.
Mods which give great advantage above others(Sobeit/airbreak, HH, Vehicle HH...) will be automatically detected.
So remove these mods if you have any of these.
Also some of buggy mods may cause problems, which corrupt your game and then some stuff get screwed up.
Take care!
Kind regards,
