Re: Smut Blocker
OpenDNS is a service worth considering; however, if you read their terms of service (Paragraph 8 - User Data), you will see Cisco is collecting data on you. They don't stipulate any particular data... which means it can be anything, such as: behavior, habits and trends.
It doesn't matter which ISP's DNS you use, you're going to notice their terms of service include a section(s) on user data (or similar) indicating they will be collecting information.
