Are children allowed to participate?

As described in the rules, the quiz is meant for young adults. We decided this as an organisation to keep the freedom to create 'adult' questions and assignments.
The minimum age to participate is 16 years. The team captain must be 18 years or older.
As an organisation, we also absolutely do not want to see children in photos and videos again. We want to be able to share the materials later and if there are children in there, that could get us into trouble
