I shouldn't even post here because this entire thread is making me facepalm all over the place but..
FP has been hacked years ago and I can't even recall when last update happened.. but honestly, who gives a shit? It still works. Wallhack and you'll get caught by @fs. Ask records the old fashioned way etc.. I honestly don't see the problem here. Back in the "old" days the only anti cheat we had was "punkbuster" and all it did was block hash commands.
I probably played agains't hackers almost every war back then, even though FP is not "safe", it still provides enough security and most people on demo like to have fun whenever they play, why would you hack? To me there is no logic in hacking.
