I find it funny that whenever BI spends 5 mins to add in a check, for example a little 1 byte packet counter, that a discussion on 'how to bypass' must be started. I think these ACs, which are so many levels behind other AC systems, are not even to be noted. It's supposed to be the other way around, you making junk and spending 5 mins and them spending an hour revamping their anti cheat due to admins/players complaining. So, you're playing right into their hands and acting like its such a struggle, putting on a nice show with a tutu and all, good job. In all seriousness if hacking was a problem they would fix it, otherwise they just add in a little check, and it would seem for the moment, 99% of them are getting kicked.
Also, I believe particularly in Arma2 that developers make it easier just so they can use 'developer cheats' and sort of test things. For example, that Benny guy who made all the warfare maps, uses godmode when he plays and no one cares. I use ESP, but rarely, as I don't usually hack since it makes it boring. However, back on point, systems like DOOACS suck because when its scripting vs scripting its usually as simple as making a variable true to bypass it. Technically it should have detected my PBO many times but it never does, cuz I haven't done anything to bypass it.
