What criteria does PICS use in deciding whats safe for my children to view? Isn that inherently a subjective decision?
Again, PICS doesn’t actually rate anything. PICS just sets technical specifications so that ratings from any source will work with all the filtering software. Rating and labeling services choose their own criteria for rating. Since rating will always involve some amount of subjective judgement, you’ll want to choose a rating service whose judgements are close to the ones you would make. The filtering software you use may already be configured to use a particular rating service, so you may not have to make this choice separately.
