- Review VPN, DNS, browser extension, and accessibility permissions.
- Decide whether bypass attempts should alert another person.

FAQ
Is a porn blocker enough by itself?
Sometimes, but not always. Blocking reduces easy access, while accountability, recovery programs, and habit trackers address different parts of the behavior loop.
What should I check before installing a blocker?
Check device coverage, bypass behavior, uninstall protection, private browsing, VPN or DNS conflicts, and whether alerts are sent to another person.
Which blocker is best for families?
Families should compare Canopy, Qustodio, Bark, Screen Time / Family Link, CleanBrowsing, and OpenDNS first because they cover filtering or family-control workflows.
