Hello,
FYI: I recently published a 1-hour video, where I demoed Pihole, alongside OpenWrt, showing 4 increasing levels of internet restriction, for younger kids (say ages 7 to 13), who may have a smartphone or tablet, but don't have a SIM card yet - so Parental control within the home LAN is moreso possible.
I showed off Pihole's Query Logs, and Adlists, which can be used as a milder form of social media restriction, or just for watching where the child's devices are connecting to (granted the kid hasn't figured out about circumventing DHCP, or use a VPN yet). Increasing restrictiveness is also shown later on (in OpenWrt). Like where to block outgoing access (by MAC address) entirely, for periods of time.
Fast-forward in to 40:12 to jump straight to the part where Pihole starts being shown.

Note: 2 Raspberry Pi's were used: one for Pihole, the other for OpenWrt.
