Don't take my post as personel MrYum. That was not my intention and if you felt that it was I sincerely apologize.
And yes, supervision and browser filters need to be implemented in every household it applies to. Filtering has 2 edges like any other sword. It's our 1st choice because there is no 2nd choice. Most filtering also causes the loss (indirectly) of web sites that are not harmful. That makes it tough for kids to use the internet as an effective educational tool.
And yes, the warning/landing/splash page is critical. If you can't reach out and grab the surfer with 'above the fold' (@800x600) 'hooks' then they are lost and gone forever.
Again, no offense intended MrYum
later ............ Larry
