There is another multi-player game that only allows name changes with aname change card.maybe Zup could start that. Brings in money for him if you really want to change, makes frivolous changes a bit more difficult. Once upon a time there was a lot of fun, and a few statements made with changing names, but now it has moved into more disruptive territory. Also maybe he should remove spaces in names, because those are often used to create a fake name without being able to spot it easily.
