Blocking More Specific Sites
It'd be useful if pages such as individual Twitter accounts or Tumblr pages, with distinct URLs could be submitted for filtering. There is so much **** on those two sites that is not caught by your filter.

Hi there, we did give this a lot of thought but it would require a huge amount of work to verify each URL. We will dedicate more time to these sites in the very near future because I agree, there is a huge amount of adult content on them.
Warm regards,
Paul
