Getting Full Steam Accounts?

I have MW2 on my other account, but i wanna play with my bro, and so i got the crack to play just Private match, but I need to buy a game to add friends... Does anyone know a way to get a game/ want to give me an account for free that just has some game downloaded?

Just download an demo.

Get a free game or a demo, As you don't have any source games so you could have mods.

I doubt you will be able to invite someone with cracked, But you got nothing to loose to try, I guess.
