Thanks for reaching out to us here in the forum! So the short answer to your question is that specific pages or videos cannot be blocked using the Custom Website List. 735Covenant Eyes blocks according the root of the domain, called the “top-level” domain. This means that our filter cannot block or allow specific parts of website - it can only block or allow the entire website. For example, you cannot block "facebook.com22" while allowing "facebook.com/my-profile27."
Additionally, depending on what Blocking Level you select, we may enforce what's called "YouTube Restricted Mode." YouTube designed and maintains this parental control feature. If you chose our Family Blocking Level, we enable and enforce YouTube Restricted Mode but YouTube controls what videos are blocked or allowed.

I hope this helps,
