The act within a game called School Vandals when people play the game as its supposed to be played (tagging rivals and cleaning tags). Other people who wish to cry foul play and dont like their low level tags being tagged over by other players.
Lyn maliciously tagged over all my tags in a tag farm. I only laid crayons down and wanted to get some easy cheap points. She has been reported to the devs.
Lesley who is also Andy and many other players, has made up some new fake accounts so that they can malicious tag the hell out of Lyn as payback for her playing the game how it was supposed to be played.
Malicious tagging is defined within the COC of School Vandals and is where a player repeatedly targets an individual or group of people on a regular basis.
