If you start hearing a little kid singing disturbing renditions of nursery songs in your Grand Theft Auto Online sessions, you better start running.
Someone who goes by the name of MrKreepyKoala has spent the last few months appearing in the multiplayer version of Los Santos and tormenting other would-be criminals by stalking and killing them. Even when his victims know what he's doing -- like becoming intangible by going into Passive Mode -- he still manages to freak them all the way out.
This is trolling at its finest, especially because there's no mean-spirited insults being flung around. Let's hope the never-talking, leather-masked psycho makes the jump to the next-gen versions of GTA V.
