Using cracked versions of steam (Steam Down for example), you won't be able to connect to legit servers. Even if a patch comes out for your cracked steam to allow you to play legit servers, after all the trouble to get it working, it takes less than a week for valve to patch up all the legit servers with an update. Also, getting a cracked version to work online playing with cracked servers is also troublesome and you would usually just find hackers/script-kiddies playing on the server using aimbot wallhack...
