I have used family safety filter for quite awhile and it does what it says it will do however I find that the web reporting is not accurate.
As an example I am consistently getting a weekly report of my childrens activities and it shows Facebook as being the #2 most used website each week despite neither of them having an account and it being blocked by Family Safety. To test I created a new account on the family PC and only had my children use the new one. Despite that the report shows their other accounts as having traffic to Facebook and other sites when they have not. There is something wrong with the reporting functionality. I can provide a report for review. I do not want to accuse my kids of something based on inaccurate information.

Let me know and thanks!
