And obvs you can use other DNS services like CTRL-D
I'm just using mullvad as an example and IMO its one of the best free DNS blocking services - you don't need a mulvard account to use it or use mulvard's VPN
CTRL-D is awesome at blocking and offers a free service but paid service is needed for most blocking you'd need - other services are kinda similar - Mullvad is IMO the best free option
