There has been a huge increase of hackers in every server and even youtube clips of people trying these hacks. This includes Godmode, infinite ammo, teleportation, vehice/item spawn and ESP hacks. This literally makes the game unplayable on most servers now as there is no point in getting gear/vehicles/tents up as they will most likely be gone no matter where you hide them in a matter of minutes. I see no way how they could prevent this anymore as most of these hacks have been in Arma 2 for sometime and unless they find a method to instantly ban a character the second their database receives corrupted/imported/sudden change in data such as teleporation then this problem will only get worse.
