it has potential, i love the idea of using it to redirect kids from inappropriate sites. there's just one big issue: The sites are right there, available to be deleted from the block list with just one click. very counterintuitive for my needs. its much too easy for anyone to simply delete and go on watching the inappropriate site, and if they weren't on the site before, they can very clearly see it along with every other blocked site and curiousity will simply lead them to click on it.
A solution could be to keep the whole block/delete segment hidden and inaccessible unless by a password or something.
