As far as Fans United is concerned, we can skip:
- The names, username and avatar. However, this will mean, that the client will have to fetch them from authentication service (e.g. Ringier Connect) each time on demand, when they want to display something. Although technicallly possible (if the authentication service supports it), it will be difficult and cumbersome to do.
- Gender, country and birth date can be skipped as well, but the breakdown in the reports will be lost. Also, specific functionality will not work. For instance, if you want to take a subsection of users who are above 18 years of age, in order to send them alcohol related ads or content.
