reminds me of a similar "ban" that happened in my country several years ago with the aim of discouraging students from wasting their time. the object of the banning, however, was trading cards rather than trading virtual items.

it did work; the vast seas of children playing cards in shopping malls and sidewalks seized to exist, but it didn't happen because children were studying. it happened because these kids switched to something else, which isn't necessarily better than the cards they banned.
