Just to let you know we released a Sample profile Generator admin module for Community Builder.
I generates sample Joomla users and CB profiles with various parameters such as gender ratio, country or regions, location coordinates, age, graduation year, job, company , fav color, blood type, current car etc...

Also every sample can be removed in one click.
