quick question for total noob

hey, i'm new to all of this, i usually play cod with a ps3 but i sold it and now i play on pc. intros aside, my question:

is there a god mode hack for mp tdm in public? if there is can someone direct me to it? and if not, where do i look for servers that allow it? and also why cant it be used in public tdm?

thanks errr'body!

Technically it is possible when you are the host (force host/luck)
But don't count on it soon
