3 levels. The third is the opt-out censorship to protect the children from file sharing, vpn & privacy related info, extreme content (gore), extreme political content (neo-Nazi, maybe even Britian First related but not confirmed), sex related, etc. By censoring file sharing & privacy related content, it does damange the "path" to becoming a programmer for some people. I know that if these were filtered by default I'd have never learnt how to program.
