disagree.
it's not just a bug that appears randomly. it's exploiting of a bug.
exploiting = using bugs to gain an unfair advantage over other players
gaining an unfair advantage over other players = cheating
BUT
cheating != hacking
hacking(ingame) = using a programm to cheat
you can cheat in many ways, not just by using third party software.
but i agree that this shouldn't get you VAC banned. but it should get you banned by the server admin.
VAC is only for hackers, not for bug exploiters. also the mechanics of VAC doesn't work that way.
people will always try to find something they can exploit. i would even say that these people are really helpful in the development progress by finding new bugs which enables the dev team to fix them.
yes and VAC only ban injecting hack ! not in game bugs !
