You don’t need a pihole. iOS and android both have parental controls that are very simple to use.

I'd be astonished if 14 and 15 year olds don't know workarounds for iOS and android child controls.

		Its harder than you think and no "state" ban will work if the 14-15 year old is smart enough to get around the child locks at the os level either. Next they will ban VPN just wait for it.
