its not a bug and it also works in higher maps,if you stay in the circle you shoot more ,with every type of ammo ,but its not permanent ,if you move around the % will last a couple of minutes maybe 2-3 minutes ,I have tried it,and that's how it works
On the lower maps (probably under 10) there is Columb with 4.5 million hp you have to shoot and next shoot small npc and stand in an orange box .. and you have to stand to time when this orange circle disappear..
,but no one got ban in global europe 1 ,and you are the 1-st I hear that got ban for that
