I tried participating in one of those once. Some step-counting competition when Fitbits were all the rage. I worked a a rather large site so I was racking up a minimum of 15,000 steps a day, so I figured I had a good shot at placing pretty high and getting some sort of prize. Because why not.

Yeah... I wasn't even close. Turns out that people who don't actually do anything love to game the system. I saw people posting 30k steps a day and more. Everyone who managed to hit top scores were just office workers who never actually visited the site. I was moving around a LOT, and to this day I have no idea how people get that high of a step count every day.

The next time HR did that competition thing, I saw a lot of the same people on the leaderboard. And multiple times after that.
