For those who don't know, most Steam games have cards that you get by spending time in the games. These cards sell for usually about 10 cents each... not much you would say, except that when you have a long list of Steam games, with 5 cards or so each, if you were to get them all you could get a nice chunk of money, say if your Steam list is 100 games, that's 500 cards or $50!
The problem is willing to play the games for so long, or leaving them running in the background would be too much a hassle for the gain, but that's where the post come from. There is an open source program I'm using called "Idle Master" (you can read the code) that basically takes your Steam list, and goes through each game and simulates that you're playing it, basically sends Steam the same calls of 'game starting' and 'game ending' that the game would send.
It's not dangerous as there is no hacking involved. The only possible problem could be if you're playing one of the VAC secured games at the same time (mostly competitive games like Counterstrike, Left 4 Dead, etc). If anything you can just run it when you're not playing and get a nice Steam credit.
