No. I mean that a badly motivated web site can pretend to offer safe material
using this but actually offer objectionable material (for whatever definition
of safe or objectionable you care to adopt). For example a site being used
to "groom" innocent victims could pretend that all its content was safe.
This would actually make the site much more dangerous than before, because
of the illusion of safety.
