I know its impossible to have no hackers at all, but I am just trying to find ways to delay their work, if have more defenses it will reduce the number of hackers, even with their existence it would be just one moment for the server admin ban the guy or you to leave the server, and with punkbuster its possible to globally ban people, like on Battlefield 4 I think, I'm sorry if I'm wrong.. I'm just speculating..
