If you want pages with the specified keywords to be allowed rather than blocked, you should select the option Treat keywords as allow-conditions rather than block-conditions under Advanced Options. If you want to block pages on any website that contain given keywords, you’ll need to use wildcards to specify all websites.
This would result in pages on the sites and being blocked only when those pages contain the complete word “anteaters” or any word beginning with “crypto” or any word ending with “alicious” or the complete phrase “green eggs and ham”.
So, for example, you could enter the following into the list of sites: Note that the keyword matching is case-insensitive (i.e., uppercase and lowercase are treated as equivalent). Within a keyword you can use an asterisk (*) to match any number of characters (except whitespace) and an underscore (_) to match whitespace. The tilde prefix (~) can be used to restrict blocking to sites that contain given keywords.
