While we have no issue with parents choosing to use filters for their kids' computers (we do have an issue when its gov't mandated, however...), we've pointed out in the past that one of the worries with such filters is that parents will over rely on those filters to actually work. Yet, history has shown time and time again that they don't work very well, and a new study out of Europe once again notes that the filters aren't very good at blocking "objectionable" content for kids
. The filters are basically good only at domain-level blocks, which is fine for some stuff, but there's all sorts of content on social networks and blogs that might not be appropriate for kids, but that these filters won't block. The simple fact is that sooner or later kids are going to see stuff they weren't meant to see. But if you rely too much on the filter, and think that it really will block stuff, you might not think to teach kids that perhaps some stuff online isn't appropriate for them, and teach them how to deal with it if they run into it by accident.
