Guys, l think l know the reason why you got ban!
1.the system probably detect something is wrong with your game especially the free bullet makes it.. Well just like that
2.the devs know you all are cheating and watching for sure..
So my suggestion is
1.this mod is need updated more
2.perhaps there is no hope for this mod for being "Free" since if its free, some people that makes the game or the devs can easily access through this website and know we are all cheating and they notice it.. So yeah.. No hope
