"Cracked" servers

[Zanz L. Barre The 3rd]

Does anyone have any experience with cracked servers used for torrented games? What sort of process does one go through to access online play through torrents?

An example would be CoD4:

I tried pokin' around for instructions but wasn't very lucky. Any help or guidance would be sweet.

Thanks!
