Well, my suggestion would be, based on what I've noticed when I changed my display name on Google Hangouts, to make a name change possible only once a month. As there was a funny message going together with the name changing dialog on Google, which was something like "Are you sure that you want to change your name? Like in real life, name changing is not an easy thing to do, so it won't be possible to change the name for another month."
