For those of you who don't want to wait any longer / got banned / don't want to get banned (exept from the server itself).
You can find a small list of cracked servers here
There are a lot more out there, but this is just an example.
All you have to do is:
1. Go ingame
2. Press F1 to bring up the console
3. Enter your prefered server ip
4. Press enter
Thats it. Have fun!
