I see the page https://docs.dnsfilter.com/docs/popular-domains on your website which is very helpful in blocking common sites. I would love to see some additional common applications which are not single domain based, that many of us in education (or otherwise) may typically want to block. This would be very helpful in saving lots of time when researching what to block. Some particulars:
Pandora
Amazon Video
Vimeo
Apple Music
Google Music
iMessage
Facetime
Fortnite network
