Then don't complain about Day Z being crap when the problem lies within the main game itself. Day Z is still in the works, so yes there will be some problems. It happens, we learn to deal with it and move on. And yes, I've seen big name MMO where a player was mass-wiping all targets. It took the team a week to locate the exploit. Even League of Legends, which is a big name PVP game, has bugs people cna exploit with ease. It happens. Hackers hack, it' what they do. If there is a way they can exploit a game, they will. But you raging won't stop it, that just emeans that they won.
