Finding Non-Punkbuster Servers

Hello, I am wondering how do you know or find out if a server is non-punk buster. The only way I can aimbot on PB servers is if I mildly use the aimbot so I do not get kicked. I want to find a good non-PB server so I can level up fast and enjoy shooting others with accuracy. (My Legit-Skills shooting days are LOOOONG gone XD). PS: First thread made if I did something wrong please let me know or fix ^^

Oh, sorry I am returning and haven't played since around 2009 XD. Thank you for informing me though!
