Writing blocking rules: syntax reference

• Prefix with @@ for exceptions
• Use || for host anchored filters
• Use @@|| to allow a list with a host anchored filter
• Append $domain=domainname.com to the end of a rule to apply that rule to a specific domain.
• Append ^$third-party to rules that apply to third parties. example: ||thirdpartydomainexample.com^$third-party
• Prefix notations with ! within a line break between rules, to describe the purpose for the next rule in the list. example: ! This rule applies for this thing which deserves notation
