Ra(n)t: Living in the Future
So Team Fortress 2 is a first-person shooter game. There are new weapons. It used to be that to get the new weapons, you had to earn achievements. For example, "kill 20 guys in one life" or "capture a control point yourself" or "go a whole round without shooting anyone". Get enough of these, earn a new weapon.

Of course, you had the "cheater servers" -- folks who would log in to servers that had games set up specifically to make "earning" these achievements easier, such as robot-players controlled by the computer who just sat there and let you kill them, etc.

The company's possible workaround? "Drops". Now merely by hanging around in a game, you can randomly earn weapons. Of course, this is even easier than a cheater server, because all you have to do is leave the computer running.

Team Fortress 2 has a friends tracker. My leaderboard is currently lit up with a dozen people ... none of whom are actually playing the game, they're just letting it run so they can be idle and their game can rack up new weapons.

When I signed up for this game, I wasn't expecting to have to wade through a listing of people who say they're playing the game, but aren't. :P
