Counter Strike Source Full Of Cheats

And This news post isn't talking about the numbers of people cheating either.

there's no anti-cheat yet
the game has built in wallhack, you can disable the sky, you can enable the overview map to show the position of ALL players - both enemy and friends; all those things are possible by simple 1-line commands

it's reason enough to pause the ladders until valve has fixed it
