First of all, thank you for this great tool. I really do appreciate it!
My question is this: Is there a way that websites with certain keywords in the URL can be blocked without having to be on the blacklist? There are a few terms that only show up in adult site URLs that do not show up in safe site URLs. I know there is the chance that some safe sites might be inadvertently blocked, but those can be manually whitelisted as people find them.
