Why am I unable to block Google or craigslist?
There is not enough information in your question for us to give you any specific help. I am guessing that you are asking about the black list web filter feature? google.com and craigslist.org are same as other websites. If it works for other sites, it should work for those two. You can also sent us a private email with your account information if it is still not working. We can check the settings to see where the issue is.
