Outgoing Filtering Perhaps the most dangerous internet safety concern for kids is the possibility that they might accidentally give away information they shouldn't. Outgoing filters can be programmed to prevent information such as name, address, telephone number, and credit card numbers from being sent to someone online. Even with kids who know and follow your rules this is a useful feature since sometimes even the best kids forget.
Some software tracks the web sites the kids visit and the activities they engage in while online.
This allows spot-checking after the fact. Just the threat of spot-checking is probably enough to keep most kids honest. The main disadvantage is that it takes extra work for someone to spot-check afterwards. This approach limits the usefulness of the Internet to such an extent that there's really no point to having Internet access any more. By eliminating the vast majority of Internet sites, these filters eliminate far more good sites than bad ones.
