Kids these days call them gecko codes (I think) where the hacker gives it to a lobby. Those lobby members leave and join another lobby and they spread it there....... Not necassarily a hacker who gave it to you, but yes a hacker originated it.
hey yes it is a hack and i think i know who it is because i was on youtube and saw about 5 videos with the same clan in them. i think its a clan called "party" because i seen them in all the videos. it might because i havent seen any other clans in in the same ones. hve u played with them?
