Yeah noone said the alliance were too awful bright ;p But I think you just basically got your name associated with multiboxing in general and people would rather yell ZINS than "MULTIBOXERS" due to laziness/famousness :p

That and as long as I can remember any time a multiboxer was found(The Disease guys, ebola & co, oathbreaker etc) in general channel everyone always calls them zins, it's an evolution of naming :p
