Use Unconventional Distractions
Team Fortress 2, a multiplayer game with no real stakes, is a great place to grief and this has been proven time and time again. The Youtube channel, V. TeamGRN shows us a perfect example of clever griefing in a video entitled “Team Fortress 2 Griefing: Hot Girl Backstabbing.”
In the video, the gamers use custom sprays to paint surfaces with pictures of women. When players stop to look at the picture, they are subsequently stabbed in the back by a cunning spy player. The best part about this griefing is that the “victims” are entirely to blame; they fell for the bait. The technique should theoretically work with any compelling image, though, so if you want to steer clear of bikini models, you still have options.
