Recognising that this is an area of concern, we have looked into the feasibility of disabling the Guest feature. Unfortunately, adding a disable guest feature to Parental Controls will not prevent cyber-savvy children from using a friend's Parental Controls-less screen name. The guest feature is actually part of the software that is installed on your computer and cannot be disabled.

With Parental Controls, we aim to provide parents with the tools they need to tailor the appropriate online experience for their children; however, because no filtering software is 100% foolproof, there is no substitute for parental supervision.
