Because it's external and doesn't modify the exe and is a read only hack which can't be modified it is "safer" to use but it depends on how you use it also. If you pick people off with FMJ through walls 24/7...yea I think you're ganna get banned in time. Don't be obvious and you'll be fine. I've still been using this for my XP machine and the other released hack for my Windows 7 machine
Although one wonders how hard it would be for the dev to actually fix the problem where one guy does not show up. Feels like the dev put a "i<full_team" instead of "i=<full_team".
Although I haven't looked at the source, so I wont say anything more.
But yeah, it does work on 95% of the players. And it now works in fullscreen on my comp. I think it was my resolution that fucked it up before, it was 1280x920, now it's 1280x720 and works perfectly.
