A lot of times people will want to create multiple accounts in order to increase the likelihood that they receive a ticket. However, this can create problems within the 1iota world as it is possible that those multiple accounts could ALL receive tickets, and then the majority of those tickets would go unused, as each member can only check-in once, and tickets are non-transferable. Often times this would result in angry fans who simply wanted to see their favorite shows, but couldn't because the tickets couldn't be transferred.
So, 1iota guidelines require that you maintain ONLY ONE 1iota account. This gives each fan an equal opportunity to get a request in, and possibly get a ticket to the show!
